 * Extlinux cannot boot from ext4 partitions with certain features enabled as documented in the [[http://www.syslinux.org/wiki/index.php?title=Filesystem#ext|syslinux wiki]].
   * Most important is the 64bit feature, which is enabled by default when creating new ext4 filsystems since e2fsprogs 1.43 (stretch). Explicitly disable this feature when creating a partition you want to boot from with extlinux by using `-O ^64bit`.
 * Booting from xfs partitions does not work, see Bug DebianBug:803938
 * There is an issue with booting from btrfs, see Bug DebianBug:865462

The SYSLINUX Project covers a suite of lightweight BootLoaders, for starting up computers operating system.

Overview

  • the original SYSLINUX, used for booting from File Allocation Table - FAT - filesystems (usually floppy discs);
  • ISOLINUX, used for booting from CD-ROM ISO 9660 filesystems;
  • PXELINUX, used for booting from a network server using the Pre-eXecution Environment (PXE) system;
  • EXTLINUX, used to boot from Linux ext2/ext3 filesystems;
  • MEMDISK, used to boot older operating systems like MS-DOS from these media.

IsoLinux :

Debian Installation CDs and DVDs (on i386, amd64, and maybe others) uses syslinux' isolinux.

PxeLinux :

Debian Installer's Netboot uses syslinux' pxelinux.
