== Q: Why does DebianInstaller always use DHCP? I want a static address! ==

'''A:''' There are currently three different ways of configuring a static IP setup:

 1. Run the installer in normal mode (select "Install") and either wait until the DHCP detection fails or cancel the DHCP detection (available in recent versions of the installer). Then you are thrown to the manual configuration of name servers. If you need to configure everything manually, you need to go back twice(!). Then select "Configure network manually". (Visit Debian Bug [[https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=794662|794662]] to see when this not very user friendly behaviour is fixed.)
 1. Run the installer in expert mode (select "Advanced options > Expert"), and you will be able to configure a static address, and many other things besides.
 1. Supply installer boot argument: 'netcfg/disable_autoconfig=true'.

Besides you may set your dhcpd to serve a fixed address to your chosen network card (identified by its mac).

== Q: But DHCP shouldn't run automatically, it breaks on my system/gets the wrong information/is not what I want. ==

'''A''': DebianInstaller is targeting a larger base of users that have historically installed Debian, including users who don't know what DHCP or static IP addresses are. Thus default behavior is chosen to use DHCP.

You can force static network configuration by providing boot parameter netcfg/disable_dhcp=true at the boot prompt.

== Q: Why are you doing this? Why not use Anaconda/PGI/whatever? Why reinvent the wheel? ==

'''A''': We're doing this because it's time. Debian has been burdened with a sub-par installer for a full decade, and it's time to change all that. Debian's installer needs to work on more platforms and more types of install media than any other. We need to support installs to S/390 mainframes that have only a teletype console. We needed to support installs to m68k boxes that boot from floppies, as well as to netbooting Sun hardware.

And yes, we want to support flashy and easy installs on Intel clones booting from CD (and USB sticks). And many more. All the [[http://www.debian.org/devel/debian-installer/|currently targeted installation methods]] are available for download.

Also installs for experienced users with higher control using the same installer are a must.

PGI can't do this. Anaconda can't do this. Only a system designed from the ground up to be completely modular and highly flexible can do so. DebianInstaller is that installer.

== Q: Is the DebianInstaller going to be graphical in nature? / Is there any prebuilt/downloadable graphical DebianInstaller? ==

'''A''': The DebianInstaller is not graphical by nature, but modularity is a key in its design and allows the use of different kinds of frontends, including a graphical one.

Since Etch, a [[DebianInstaller/GUI|graphical version of the installer]] is available for i386, amd64. For powerpc the graphical installer is only available as a separate, experimental image.

See the [[http://www.debian.org/releases/stable/installmanual|Installation Guide]] for further information.

== Q: Does the DebianInstaller support creating and installing to software RAID devices? ==

'''A''': The installer supports software RAID levels 0, 1, 4, 5, 6 and 10, and [[DebianInstaller/SataRaid|SATA RAID]]. Note that if you use RAID for /boot, you will be forced to use lilo since grub doesn't support RAID.
(DebianBug:251905).

If you do not need to dual boot to MS Windows installed on such a RAID system, please use the DebianInstaller default (software) RAID manager ([[http://packages.debian.org/mdadm|mdadm]]) as listed above: it is far better tested and seems equally fast.

== Q: How do I install using LVM? Is there any more information about using the LVM installer? LVM installation doesn't work! ==

'''A''': LVM is fairly straightforward to configure using the menu item in the partitioner titled "Configure the Logical Volume Manager". Please note that it will probably help a lot if you know some [[http://www.tldp.org/HOWTO/LVM-HOWTO/|LVM terminology]] - it's recommended that you know the following three concepts: volume group (VG), physical volume (PV) and logical volume (LV) and how these relate to each other.

You can even build an LVM on top of a RAID device even for root. Nevertheless Grub has still some troubles (DebianBug:251905).

Recent versions of the installer can also set up LVM as part of the guided partitioning process.

== Q: DebianInstaller does not include a driver for my xyz network card, but I have (tarball) driver sources. What are the steps for building that driver? ==

'''A''': It's possible to do this, but we do not yet have good end-user docs explaining how to do so. We're waiting for an end user to accomplish it and write them from experience. We're glad to help you through the process when you mail us at debian-boot@lists.debian.org (do not forget to add lspci -v output).

See also DebianInstaller/NetInstWithThirdPartyNetworkDriver for a lengthy manual procedure of re-packaging netinst with a regular Debian kernel and the third party driver compiled against it. That procedure should give way to the install-time compilation of the driver against the installer's and the target kernels, a la module-assistant.

== Q: How do I install using the hd-media? ==

'''A''': A [[https://www.debian.org/distrib/netinst|netinst]] or [[https://www.debian.org/CD/http-ftp/#stable|CD/DVD]] installation image can be booted directly from a hard disk (or [[https://wiki.debian.org/Installation+Archive+USBStick|a USB drive]]) using [[https://www.debian.org/releases/stable/amd64/ch05s01.html.en#boot-initrd|LILO or GRUB]]. For GRUB, ''/etc/grub.d/40_custom'' would be a convenient place to put a stanza; then run `update-grub`. An hd-media kernel (linux) and an initrd (initrd.gz) for the Debian 9 i-386 architecture are available [[http://deb.debian.org/debian/dists/stretch/main/installer-i386/current/images/netboot/debian-installer/i386/|here]].

After selecting the entry in the boot menu to boot from, the ISO is [[https://www.debian.org/releases/stable/amd64/ch06s03.en.html#di-setup|searched for]] and, when found, mounted using the initrd's loop module. From there the Debian installer takes over and installation of the OS proceeds as normal.

== Q: How can I create boot iso with my own set of packages? ==

'''A''': see [[DebianInstaller/Modify]]

== Q: How can I build the DebianInstaller? ==

'''A''': see [[DebianInstaller/Build]]

== Q: Why doesn't the installer automatically choose the appropriate kernel to install (for example an i686 kernel instead of the generic i386)? ==

'''A''': The netinst CD image includes only the generic i386 kernel, so if you're using that you will always have install the proper kernel for your system manually after the installation if you want an optimized version. Including all the kernels on the netinst CD would use too much space.

If using any other installation method than the netinst CD you should get a kernel installed that is optimized for your hardware.

Update: recent netinst images also include the 686 flavor of the kernel.

== Q: What about SMP support? ==

'''A''': The installer itself does not need any SMP support and will not boot with an SMP enabled kernel since it merely needs to install the system to your machine.

When the system is being installed, the installer attempts to automatically detect SMP and chose and the appropriate kernel, so that SMP is enabled when you boot into your newly installed Debian system. If it fails to notice that it needs a SMP kernel on your machine, please file a [[https://www.debian.org/releases/stable/i386/ch05s04.html#submit-bug|detailed installation report]].

On some architectures (including i386 and amd64), the standard Debian kernel image has been compiled with SMP-alternatives support. This means that the kernel will detect the number of processors (or processor cores) and will automatically deactivate SMP on uniprocessor systems.

== Q: Why isn't the installed system configured to use the language I chose during installation? ==

'''A''': This problem has been fixed, so if you see it using any current image, please file a detailed installation report.

== Q: When I run the DebianInstaller, my keyboard doesn't work! ==

'''A''': This seems to be especially common on laptops. Try booting with no APIC and no local APIC support ("boot: linux noapic nolapic").

== Q: Why isn't my hardware supported by DebianInstaller, I know there is a Linux driver for it! ==

'''A''': Some firmwares do not meet the requirements of DFSG (the Debian Free Software Guidelines) and are therefore distributed separately from Debian proper, in the ''non-free'' area of our archive: [[http://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/|installer iso image file]] , [[http://cdimage.debian.org/cdimage/unofficial/non-free/firmware/|firmware driver file]]. See section 2.2 (Devices Requiring Firmware) of [[http://www.debian.org/releases/stable/installmanual|the installation guide]] for detailed instructions.

== Q: There seem to be errors reading the CD! ==

'''A''': First of all, check that the [[MD5]]-sum of the ISO file you downloaded is correct; the md5sum for each of the [[ISOs]] is available in the same directory as the ISO download. After booting the installer you can also check the CD-ROM: use the {{{<go back>}}} button to back up to the main menu and select the option to check the CD-ROM's integrity.

If you are positive that the CD is correct, it could be that the CD-ROM is old and/or flaky when using DMA. You can try disabling DMA for the CD-ROM (by booting with "linux ide=nodma").

You can also disable DMA using the following procedure.
 * switch to VT2 (using alt-F2)
 * {{{cd /proc/ide/hdX}}} ({{{X}}} varies depending on where your CD drive is connected)
 * {{{cat settings}}}
 * check the current setting for using_dma
 * change it using the command {{{echo "using_dma:0" >settings}}} (or ":1")
 * switch back to VT1 (using alt-F1)

A tightly folded IDE cable can also cause read errors, try repositioning the cable.

== Q: How can I install sid (unstable) with DebianInstaller? ==

'''A''': A very common and reliable method to install sid is first to install {{{stable}}} using a [[https://www.debian.org/distrib/netinst|netinst]] or [[https://www.debian.org/CD/http-ftp/|DVD-1]] image and then upgrade to {{{unstable}}} after altering ''/etc/apt/sources.list'' to have the single line

{{{
deb http://deb.debian.org/debian unstable main
}}}

If the sole purpose is to end up with an unstable installation, it is probably best to skip to installing the boot loader after the base files have been installed. This gives a minimal system to work with and saves time.

It is not possible to install sid directly from a netinst or full DVD but it can be done using the [[http://deb.debian.org/debian/dists/stretch/main/installer-i386/current/images/netboot/|mini.iso]] provided as part of the [[https://www.debian.org/distrib/netinst|network boot]] installation method.
Start the installation in expert mode. Mirror selection comes early in the process and you will be asked which distribution to install: stable, testing or unstable.

== Q: How do I copy d-i logfiles to a remote host? ==

'''A''': Use the included mini web server.

 1. Get to the main menu and choose the "Save debug logs" menu item.
 1. Tell it to start up the web server, and follow the prompts to download the logs from the web server to your other computer.

 You can also use "apt-get install installation-report reportbug; reportbug installation-report" and follow the prompts to let it download the log files for you and produce a nice installation report.

'''A''': Use the mini ssh client to push log files to a different host. See [[DebianInstaller/AsSshClient]].

== Q: How do I install via PPPoE? ==

'''A''': Debian Installer, starting with February 2007, supports installing a system via PPPoE and will configure the system accordingly. At the regular Debian Installer boot line just append modules=ppp-udeb.

{{{
e.g.: type "installgui modules=ppp-udeb" to start a graphical installation via PPPoE
}}}

Installing via PPPoE is not supported yet for installations done via netboot.

More information in the [[http://d-i.debian.org/manual/en.i386/apds05.html|corresponding chapter in the Installation Guide]].

== Q: How do I use netinst over PPP? ==

'''A''': With the '''''netinst''''' CD-ROM image, or a full CD or DVD, you can set up PPP after the system is installed.

'''PPP''' configuration is provided by {{{pppconfig}}}.
Be aware that so called winmodems are not supported yet!

== Q: What do I do if I can no longer boot Windows after installing Debian? ==

'''A''': If all goes well, DebianInstaller should automatically add a working menu item for an existing Windows installation.

If no menu item was added, please file a [[https://www.debian.org/releases/stable/i386/ch05s04.html#submit-bug|detailed installation report]].
If you are using GRUB as your bootloader, add the following lines at the end of the file /boot/grub/menu.lst:{{{
  title Windows
  root (hd0,0)
  savedefault
  makeactive
  chainloader +1
}}}
You should change (hd0,0) to refer to the correct partition: (hd0,0) is Grub's notation for the first partition on the first harddisk ({{{/dev/hda1}}} or {{{/dev/sda1}}}); (hd1,3) is the fourth partition on the second harddisk ({{{/dev/hdb4}}}).
If you are using LILO as your bootloader, add the following lines at the end of the file {{{/etc/lilo.conf}}}:{{{
  other=/dev/hda1
        label=Windows
}}}
Again, change {{{/dev/hda1}}} to refer to your Windows partition. After updating this file, you will need to run 'lilo' as root.

If there is a menu entry, but you get errors when you try to boot Windows
There could be different reasons for this. First you should check that the configuration of your bootloader is correct. See above for some pointers.

== Q: Can I use d-i as a rescue system? What pitfalls are there? ==

'''A''': Yes, you can use d-i to mount your hard disks and fix {{{/etc/shadow}}} if you forgot your password.

And you can also use d-i to boot your system to chroot into your installation and execute your boot-loader (grub, lilo, yaboot, ...) if you cannot boot from hard disk any more.

Just boot the installer with "rescue" and follow the prompts until it mounts your hard disk and gives you a shell chrooted into your system.

Alternatively, just boot the installation system as if you were starting a new installation, proceed to the point where you get to partitioning harddisks and '''stop there'''. Next, switch to VT2 (using alt-F2) or back out to the menu and start a shell from there. Create a directory {{{/target}}}, manually mount the partition(s) where you installed Debian on {{{/target}}} and execute {{{chroot /target}}}.
You cannot use the d-i menu item "install boot-loader" because the menu systems uses dependencies which require a Debian install (on a clean partition...), which you don't want.

== Q: How to use preseeding? How to use network console with preseeding? ==

'''A''': see [[DebianInstaller/Preseed]] and DebianInstaller/NetworkConsole

== Q: How to shrink an existing Windows installation? ==

'''A''': Please see the Installation Guide, chapter 6.3.3.3 (Manual Partitioning). Basically, you need to select the item displaying the size of the partition to change the size. Please make sure that you check the partition for correctness before (best with chkdsk), and that you have a backup of your data, and also are able to re-install Windows (or forget about it totally) in case something breaks.

== Q: What types of media are available? What versions are available? Where to download? ==

'''A''': See http://www.debian.org/devel/debian-installer/

== Q: Your amd64 CD does not boot. I downloaded it from http://someplace/foo/ia64/bar ==

'''A''': The ia64 architecture is not the same as the amd64 architecture and you downloaded the wrong CD image.

== Q: Why is ping not available in the debug shell ==

'''Note: as of Wheezy Debian Installer Beta 3, ping is now available.'''

'''A''': Every utility that is included uses valuable memory, so the installer is as lean as possible and ping is just not essential.

To test connections to other hosts, you can use {{{wget}}} instead:{{{
wget http://hostname
}}}
You can tell a lot from the answers {{{wget}}} returns; some examples:
 * host can be reached and is a webserver: an {{{index.html}}} file will be downloaded
 * host can be reached but is not a webserver: 'Connection refused'
 * host exists (IP address resolved), but cannot be reached: 'No route to host'
 * DNS works but IP address cannot be resolved: 'Name or service not known'
 * DNS does not work: 'Temporary failure in name resolution'

== Q: Running the installer from an iso file on a hdd requires a kernel, such as vmlinuz, ... ==
... and initrd [[https://en.wikipedia.org/wiki/RAM_disk|RAM disk]], such as initrd.gz. Can the vmlinuz and initrd.gz in the iso file be extracted and used as in [[https://wiki.debian.org/DebianLive/MultibootISO|many old examples]]?

'''A''': No. The vmlinuz and initrd.gz in the iso file serve when booting from an optical drive. When an iso file is used directly from a HDD, "hd-media" vmlinuz and initrd.gz are required. For the Debian stable release the files are in the [[http://ftp.debian.org/debian/dists/stable/main/installer-i386/current/images/hd-media/|"hd-media" directory]].

----

----

'''Question 1''': The installer detects my ethernet card and loads the proper modules for it, but when I reboot, no drivers are loaded (the card doesn't work).

'''Answer''': This is most probably a known problem with discover-data. The problem will go away once discover-data is upgraded to a more recent version. This should have already happened now, so if you see the problem, let us know.

----

'''Question 2''': Why does DebianInstaller always use DHCP? I want a static address!

'''Answer''': There are currently two different ways of configuring a static IP setup:

 1. Run in normal mode and wait when the DHCP step is performed, if it fails you are given the option of configuring a static setup.
 1. Boot the installer in expert mode ("boot: expert"), and you will be able to configure a static address, and many other things besides. (Press F2 in boot screen for more information.)

----

'''Question 3''': But DHCP shouldn't run automatically, it breaks on my system/gets the wrong information/is not what I want.

'''Answer''': DebianInstaller is targeting a larger base of users than have historically installed Debian, including users who don't know what DHCP or static IP addresses are. Thus default behavior is chosen to use DHCP.

You can force static network configulation by providing boot parameter netcfg/use_dhcp=false at the boot prompt. (Press F7 in boot screen for more information.)

----

'''Question 4''': Why are you doing this? Why not use Anaconda/PGI/whatever? Why reinvent the wheel?

'''Answer''': We're doing this because it's time. Debian has been burdened with a sub-par installer for a full decade, and it's time to change all that. Debian's installer needs to work on more platforms and more types of install media than any other. We need to support installs to S/390 mainframes that have only a teletype console. We need to support installs to m68k boxes that boot from floppies, as well as to netbooting Sun hardware.

And yes, we want to support flashy easy installs on Intel clones booting from CD (and USB sticks). And many more; all the currenly targeted installation methods are listed [http://www.debian.org/devel/debian-installer/ports-status here].

PGI can't do this. Anaconda can't do this. Only a system designed from the ground up to be completly modular and highly flexible can do so. DebianInstaller is that installer.

----

'''Question 5''': Is the DebianInstaller going to be graphical in nature? / Is there any prebuilt/downloadable graphical DebianInstaller?

'''Answer''': The DebianInstaller will not be graphical by nature, but modularity is a key in its design. It would allow the use of different kinds of frontends, including those of a graphical nature.

There is a project underway to create a GTK frontend to the installer. For more information on the current status of this frontend see [http://www.debian.org/devel/debian-installer/gtk-frontend here]. Unfortunately the project hasn't seen much activity lately.

----

'''Question 6''': Will the DebianInstaller support creating and installing to software RAID devices?

'''Answer''': Paul Fleischer implemented a test image,
whose support will be soon merged. Take a look at his [http://lists.debian.org/debian-boot/2004/debian-boot-200404/msg01003.html list posting] from debian-boot.

----

'''Question 7''': How do I install using LVM? Is there any more information about using the LVM installer? LVM installation doesn't work!

'''Answer''': As of beta3 or later, LVM is fairly straightforward to configure using the menu item in the partitioner titled "Configure the Logical Volume Manager". Please note that it will probably help a lot if you know some [http://www.tldp.org/HOWTO/LVM-HOWTO/ LVM terminology] - it's recommended that you know the following three concepts: volume group (VG), physical volume (PV) and logical volume (LV) and how these relate to each other.

Currently, there are two bugs that currently make installation of LVM less than ideal ([http://bugs.debian.org/237466 237466] and [http://bugs.debian.org/239068 239068]). If you feel that you do not have some experience in hand-fixing installation problems you might want to wait until these have been resolved.

Also please note that LVM support is scheduled to change from being based on ["LVM1"] to based on ["LVM2"] (more information [http://bugs.debian.org/224661 here]). ["LVM2"] is based upon the device-mapper which is patched into Debian packaged 2.4 kernels (since 2.4.23) and available in ["vanilla"] 2.6 ["kernel"]s. Thus you might want to wait for the transition to be done in order to get a more "future-proof" system (additionally, the device-mapper provides the foundation for software RAID and other goodies).

----

'''Question 8''': Is installation on SATA harddrives supported by DebianInstaller?

'''Answer''': There are currently three options for SATA users:

 1. Get the [http://www.debian.org/devel/debian-installer/ latest beta] or [http://cdimage.debian.org/pub/cdimage-testing/daily/ daily build] of the DebianInstaller, the 2.4.25 kernel includes some support for SATA. This is expected to improve later as the kernel package used in the installer is updated to 2.4.26-2 or later where the SATA drivers have been included (as announced [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=246053 here]).
 1. Install using the Linux 2.6 kernel which should have support for your SATA hardware (boot the installer with "linux26").
 1. See if you can change your SATA settings in the BIOS from somethink like "Native mode" to "Compability mode" (might be labeled differently)

----

'''Question 9''': DebianInstaller does not include a driver for my xyz network card, but I have (tarball) driver sources. What are the steps for building that driver? Do the steps include the phrase, "Assume you have kernel-headers?" Do you think you'll be able to include kernel-headers for the installer's kernel image(s) in the CD image, so we don't have to sneaker-net them around?

'''Answer''': It's possible to do this, but we do not yet have good end-user docs explaining how to do so. We're waiting for an end user to accomplish it and write them from experience. We're glad to help you through the process when you mail us at debian-boot@lists.debian.org (do not forget to add lspci -v output).

----

'''Question 10''': Will there be support for Linux 2.6 kernels?

'''Answer''': Boot with "linux26" for rather experimental support.

----

'''Question 11''': How to install with boot floppies + netinst.iso mounted as a loop device in the ramdisk from a ext2 partition?

'''Answer''': ??

----

'''Question 12''': How can I create boot iso with my own set of packages?

'''Answer''': see DebianInstallerModify

----

'''Question 13''': How can I build the DebianInstaller?

'''Answer''': see DebianInstallerBuild

----

'''Question 14''': What's the difference between dhcp-client and dhcpcd ?

Context: I'm testing beta 3 of the Debian-Installer
http://www.debian.org/devel/debian-installer/
.

When I install debian on a fresh machine and select "testing" and, inside tasksel, choose only{{{
  [*] Broadband internet connection
}}}
, then it removes "dhcp-client" and installs "dhcpcd".

Why ? "dhcp-client" was working fine during the previous net-install.

'''Answer''': Well dhcpcd conflicts with dhcp-client ..
you might want to fill a wishlist bug for tasksel
to better include already provided dhcp-client:
[http://bugs.debian.org bug tracking system]

----

'''Question 15''': Why after installer tells me its finished and reboot it ejects the cdrom and then after the machine start up, it enters the welcome debian screen, but then it keep rebooting?

'''Answer''': ???

----

'''Question 16''': Why does the installer ask for the ide-scsi module to install the system, when it clearly can use the normal ide-cd module to do this? Why is the ide-scsi module not included on the cd install, and where can we get it (I have tried the cd drivers boot floppy, no good)?

'''Answer''': ???

----

'''Question 17''': Why do I have to choose twice which mirror to use (at installation and later when base-config is performed)?

'''Answer''': This is a known bug and it's being worked on (see bug number [http://bugs.debian.org/220269 220269] for the current status).

----

'''Question 18''': Why doesn't the installer automatically choose the appropriate kernel to install (for example an i686 kernel instead of the generic i386)?

'''Answer''': This is bug [http://bugs.debian.org/237529 237529] and it should be fixed by now. If you still see this problem in a recent installer, please reopen that bug and include the content of /proc/cpuinfo and which kernel version should be installed for your processor.

----

'''Question 19''': What about SMP support?

'''Answer''': The installer itself does not need any SMP support and will not boot with an SMP enabled kernel since it merely needs to install the system to your machine.

When the system is being installed, it would be nice if SMP was automatically detected and the appropriate kernel was chosen though (which would mean that SMP was enabled when you boot into your newly installed Debian system).

There is currently a bug filed against the DebianInstaller, requesting this feature. You can see it's current status by looking at [http://bugs.debian.org/246483 the bug report].

----

'''Question 20''': Why isn't the installed system configured to use the language I chose during installation?

'''Answer''': This problem will likely remain until bugs [http://bugs.debian.org/237387 237387] and [http://bugs.debian.org/244475 244475] are fixed. If you still experince problems with an installer version which is released after these two are fixed, please reopen the appropriate bug.

----

'''Question 21''': Why isn't X configured to use the keyboard I chose during installation?

'''Answer''': This is a known problem, to check if it has been fixed or to track it's progress, see bug report [http://bugs.debian.org/238778 238778].

----

'''Question 22''': When I run the DebianInstaller, my keyboard doesn't work!

'''Answer''': This seems to be especially common on laptops. Try booting with no APIC and no local APIC support ("boot: linux noapic nolapic").

----

'''Question 23''': Why isn't my NIC supported by DebianInstaller, I know the "tg3" driver supports it!

'''Answer''': As tg3 contains firmware which does not seem to meet the requirements of DFSG (the Debian Free Software Guidelines), a decision has been made to remove the driver from debian packaged kernels (more information [http://lists.debian.org/debian-devel/2004/04/msg05149.html here] and [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=239952 here]). The tg3 driver is currently still in the 2.4 kernels though, so a workaround would be to make an installation with 2.4 and then compile your own version of the 2.6 kernel which includes the tg3 driver.

----

'''Question 24''': There seems to be errors reading the CD!

'''Answer''': First of all, check that the ["MD5"]-sum of the ISO file you downloaded is correct. If you are positive that the CD is correct, it could be that the CD-ROM is old and/or flaky when using DMA. Try disabling DMA for the CD-ROM (by booting with "linux ide=nodma"), unfortunately this boot option is currently broken (see bug [http://bugs.debian.org/226057 226057]).

----

'''Question 25''': How can I install sid (unstable) with DebianInstaller?

'''Answer''': You have to use a sid (unstable) version of the DebianInstaller which can be found [http://cdimage.debian.org/pub/cdimage-testing/sid_d-i/ here].

----

'''Question 26''': Why do I have to choose between ru and ru_RU in keymap chooser? Why choosing ru_RU gives unreadable messages after loading fresh Debian? (I tried installing Beta 4).

'''Answer''': ???

Note

Before attempting an installation or reporting a problem, remember to check the errata page (either the errata of Debian/Stable D-I or the errata of DI Development version) to see if your problem is already well known.

If you are experiencing problems with an older version of the installer, please try a more recent version from the Debian-Installer home page, as your problem might already be solved.

Please don't edit this page to ask new questions here! This page is only for frequently asked questions. Please do edit this page to add questions that you know are frequently asked, or to improve the answers.


Q: Why does DebianInstaller always use DHCP? I want a static address!

A: There are currently three different ways of configuring a static IP setup:

  1. Run the installer in normal mode (select "Install") and either wait until the DHCP detection fails or cancel the DHCP detection (available in recent versions of the installer). Then you are thrown to the manual configuration of name servers. If you need to configure everything manually, you need to go back twice(!). Then select "Configure network manually". (Visit Debian Bug 794662 to see when this not very user friendly behaviour is fixed.)

  2. Run the installer in expert mode (select "Advanced options > Expert"), and you will be able to configure a static address, and many other things besides.

  3. Supply installer boot argument: 'netcfg/disable_autoconfig=true'.

Besides you may set your dhcpd to serve a fixed address to your chosen network card (identified by its mac).

Q: But DHCP shouldn't run automatically, it breaks on my system/gets the wrong information/is not what I want.

A: DebianInstaller is targeting a larger base of users that have historically installed Debian, including users who don't know what DHCP or static IP addresses are. Thus default behavior is chosen to use DHCP.

You can force static network configuration by providing boot parameter netcfg/disable_dhcp=true at the boot prompt.

Q: Why are you doing this? Why not use Anaconda/PGI/whatever? Why reinvent the wheel?

A: We're doing this because it's time. Debian has been burdened with a sub-par installer for a full decade, and it's time to change all that. Debian's installer needs to work on more platforms and more types of install media than any other. We need to support installs to S/390 mainframes that have only a teletype console. We needed to support installs to m68k boxes that boot from floppies, as well as to netbooting Sun hardware.

And yes, we want to support flashy and easy installs on Intel clones booting from CD (and USB sticks). And many more. All the currently targeted installation methods are available for download.

Also installs for experienced users with higher control using the same installer are a must.

PGI can't do this. Anaconda can't do this. Only a system designed from the ground up to be completely modular and highly flexible can do so. DebianInstaller is that installer.

Q: Is the DebianInstaller going to be graphical in nature? / Is there any prebuilt/downloadable graphical DebianInstaller?

A: The DebianInstaller is not graphical by nature, but modularity is a key in its design and allows the use of different kinds of frontends, including a graphical one.

Since Etch, a graphical version of the installer is available for i386, amd64. For powerpc the graphical installer is only available as a separate, experimental image.

See the Installation Guide for further information.

Q: Does the DebianInstaller support creating and installing to software RAID devices?

A: The installer supports software RAID levels 0, 1, 4, 5, 6 and 10, and SATA RAID. Note that if you use RAID for /boot, you will be forced to use lilo since grub doesn't support RAID. (251905).

If you do not need to dual boot to MS Windows installed on such a RAID system, please use the DebianInstaller default (software) RAID manager (mdadm) as listed above: it is far better tested and seems equally fast.

Q: How do I install using LVM? Is there any more information about using the LVM installer? LVM installation doesn't work!

A: LVM is fairly straightforward to configure using the menu item in the partitioner titled "Configure the Logical Volume Manager". Please note that it will probably help a lot if you know some LVM terminology - it's recommended that you know the following three concepts: volume group (VG), physical volume (PV) and logical volume (LV) and how these relate to each other.

You can even build an LVM on top of a RAID device even for root. Nevertheless Grub has still some troubles (251905).

Recent versions of the installer can also set up LVM as part of the guided partitioning process.

Q: DebianInstaller does not include a driver for my xyz network card, but I have (tarball) driver sources. What are the steps for building that driver?

A: It's possible to do this, but we do not yet have good end-user docs explaining how to do so. We're waiting for an end user to accomplish it and write them from experience. We're glad to help you through the process when you mail us at debian-boot@lists.debian.org (do not forget to add lspci -v output).

See also DebianInstaller/NetInstWithThirdPartyNetworkDriver for a lengthy manual procedure of re-packaging netinst with a regular Debian kernel and the third party driver compiled against it. That procedure should give way to the install-time compilation of the driver against the installer's and the target kernels, a la module-assistant.

Q: How do I install using the hd-media?

A: A netinst or CD/DVD installation image can be booted directly from a hard disk (or a USB drive) using LILO or GRUB. For GRUB, /etc/grub.d/40_custom would be a convenient place to put a stanza; then run update-grub. An hd-media kernel (linux) and an initrd (initrd.gz) for the Debian 9 i-386 architecture are available here.

After selecting the entry in the boot menu to boot from, the ISO is searched for and, when found, mounted using the initrd's loop module. From there the Debian installer takes over and installation of the OS proceeds as normal.

Q: How can I create boot iso with my own set of packages?

A: see DebianInstaller/Modify

Q: How can I build the DebianInstaller?

A: see DebianInstaller/Build

Q: Why doesn't the installer automatically choose the appropriate kernel to install (for example an i686 kernel instead of the generic i386)?

A: The netinst CD image includes only the generic i386 kernel, so if you're using that you will always have install the proper kernel for your system manually after the installation if you want an optimized version. Including all the kernels on the netinst CD would use too much space.

If using any other installation method than the netinst CD you should get a kernel installed that is optimized for your hardware.

Update: recent netinst images also include the 686 flavor of the kernel.

Q: What about SMP support?

A: The installer itself does not need any SMP support and will not boot with an SMP enabled kernel since it merely needs to install the system to your machine.

When the system is being installed, the installer attempts to automatically detect SMP and chose and the appropriate kernel, so that SMP is enabled when you boot into your newly installed Debian system. If it fails to notice that it needs a SMP kernel on your machine, please file a detailed installation report.

On some architectures (including i386 and amd64), the standard Debian kernel image has been compiled with SMP-alternatives support. This means that the kernel will detect the number of processors (or processor cores) and will automatically deactivate SMP on uniprocessor systems.

Q: Why isn't the installed system configured to use the language I chose during installation?

A: This problem has been fixed, so if you see it using any current image, please file a detailed installation report.

Q: When I run the DebianInstaller, my keyboard doesn't work!

A: This seems to be especially common on laptops. Try booting with no APIC and no local APIC support ("boot: linux noapic nolapic").

Q: Why isn't my hardware supported by DebianInstaller, I know there is a Linux driver for it!

A: Some firmwares do not meet the requirements of DFSG (the Debian Free Software Guidelines) and are therefore distributed separately from Debian proper, in the non-free area of our archive: installer iso image file , firmware driver file. See section 2.2 (Devices Requiring Firmware) of the installation guide for detailed instructions.

Q: There seem to be errors reading the CD!

A: First of all, check that the MD5-sum of the ISO file you downloaded is correct; the md5sum for each of the ?ISOs is available in the same directory as the ISO download. After booting the installer you can also check the CD-ROM: use the <go back> button to back up to the main menu and select the option to check the CD-ROM's integrity.

If you are positive that the CD is correct, it could be that the CD-ROM is old and/or flaky when using DMA. You can try disabling DMA for the CD-ROM (by booting with "linux ide=nodma").

You can also disable DMA using the following procedure.

  • switch to VT2 (using alt-F2)
  • cd /proc/ide/hdX (X varies depending on where your CD drive is connected)

  • cat settings

  • check the current setting for using_dma
  • change it using the command echo "using_dma:0" >settings (or ":1")

  • switch back to VT1 (using alt-F1)

A tightly folded IDE cable can also cause read errors, try repositioning the cable.

Q: How can I install sid (unstable) with DebianInstaller?

A: A very common and reliable method to install sid is first to install stable using a netinst or DVD-1 image and then upgrade to unstable after altering /etc/apt/sources.list to have the single line

deb http://deb.debian.org/debian unstable main

If the sole purpose is to end up with an unstable installation, it is probably best to skip to installing the boot loader after the base files have been installed. This gives a minimal system to work with and saves time.

It is not possible to install sid directly from a netinst or full DVD but it can be done using the mini.iso provided as part of the network boot installation method. Start the installation in expert mode. Mirror selection comes early in the process and you will be asked which distribution to install: stable, testing or unstable.

Q: How do I copy d-i logfiles to a remote host?

A: Use the included mini web server.

  1. Get to the main menu and choose the "Save debug logs" menu item.
  2. Tell it to start up the web server, and follow the prompts to download the logs from the web server to your other computer. You can also use "apt-get install installation-report reportbug; reportbug installation-report" and follow the prompts to let it download the log files for you and produce a nice installation report.

A: Use the mini ssh client to push log files to a different host. See DebianInstaller/AsSshClient.

Q: How do I install via PPPoE?

A: Debian Installer, starting with February 2007, supports installing a system via PPPoE and will configure the system accordingly. At the regular Debian Installer boot line just append modules=ppp-udeb.

e.g.: type "installgui modules=ppp-udeb" to start a graphical installation via PPPoE

Installing via PPPoE is not supported yet for installations done via netboot.

More information in the corresponding chapter in the Installation Guide.

Q: How do I use netinst over PPP?

A: With the netinst CD-ROM image, or a full CD or DVD, you can set up PPP after the system is installed.

PPP configuration is provided by pppconfig. Be aware that so called winmodems are not supported yet!

Q: What do I do if I can no longer boot Windows after installing Debian?

A: If all goes well, DebianInstaller should automatically add a working menu item for an existing Windows installation.

If no menu item was added, please file a detailed installation report. If you are using GRUB as your bootloader, add the following lines at the end of the file /boot/grub/menu.lst:

  title           Windows
  root            (hd0,0)
  savedefault
  makeactive
  chainloader     +1

You should change (hd0,0) to refer to the correct partition: (hd0,0) is Grub's notation for the first partition on the first harddisk (/dev/hda1 or /dev/sda1); (hd1,3) is the fourth partition on the second harddisk (/dev/hdb4). If you are using LILO as your bootloader, add the following lines at the end of the file /etc/lilo.conf:

  other=/dev/hda1
        label=Windows

Again, change /dev/hda1 to refer to your Windows partition. After updating this file, you will need to run 'lilo' as root.

If there is a menu entry, but you get errors when you try to boot Windows There could be different reasons for this. First you should check that the configuration of your bootloader is correct. See above for some pointers.

Q: Can I use d-i as a rescue system? What pitfalls are there?

A: Yes, you can use d-i to mount your hard disks and fix /etc/shadow if you forgot your password.

And you can also use d-i to boot your system to chroot into your installation and execute your boot-loader (grub, lilo, yaboot, ...) if you cannot boot from hard disk any more.

Just boot the installer with "rescue" and follow the prompts until it mounts your hard disk and gives you a shell chrooted into your system.

Alternatively, just boot the installation system as if you were starting a new installation, proceed to the point where you get to partitioning harddisks and stop there. Next, switch to VT2 (using alt-F2) or back out to the menu and start a shell from there. Create a directory /target, manually mount the partition(s) where you installed Debian on /target and execute chroot /target. You cannot use the d-i menu item "install boot-loader" because the menu systems uses dependencies which require a Debian install (on a clean partition...), which you don't want.

Q: How to use preseeding? How to use network console with preseeding?

A: see DebianInstaller/Preseed and DebianInstaller/NetworkConsole

Q: How to shrink an existing Windows installation?

A: Please see the Installation Guide, chapter 6.3.3.3 (Manual Partitioning). Basically, you need to select the item displaying the size of the partition to change the size. Please make sure that you check the partition for correctness before (best with chkdsk), and that you have a backup of your data, and also are able to re-install Windows (or forget about it totally) in case something breaks.

Q: What types of media are available? What versions are available? Where to download?

A: See http://www.debian.org/devel/debian-installer/

Q: Your amd64 CD does not boot. I downloaded it from http://someplace/foo/ia64/bar

A: The ia64 architecture is not the same as the amd64 architecture and you downloaded the wrong CD image.

Q: Why is ping not available in the debug shell

Note: as of Wheezy Debian Installer Beta 3, ping is now available.

A: Every utility that is included uses valuable memory, so the installer is as lean as possible and ping is just not essential.

To test connections to other hosts, you can use wget instead:

wget http://hostname

You can tell a lot from the answers wget returns; some examples:

  • host can be reached and is a webserver: an index.html file will be downloaded

  • host can be reached but is not a webserver: 'Connection refused'
  • host exists (IP address resolved), but cannot be reached: 'No route to host'
  • DNS works but IP address cannot be resolved: 'Name or service not known'
  • DNS does not work: 'Temporary failure in name resolution'

Q: Running the installer from an iso file on a hdd requires a kernel, such as vmlinuz, ...

... and initrd RAM disk, such as initrd.gz. Can the vmlinuz and initrd.gz in the iso file be extracted and used as in many old examples?

A: No. The vmlinuz and initrd.gz in the iso file serve when booting from an optical drive. When an iso file is used directly from a HDD, "hd-media" vmlinuz and initrd.gz are required. For the Debian stable release the files are in the "hd-media" directory.
