?wiki:initramfs-tools is used in Debian to build the initramfs that contains the early userspace and the needed kernel modules to be able to mount any possible root.

Debug Howto

  • Check root device existance
     ls -l /dev/[hs]da*
  • Check root boot argument
    • It needs to be the same than aboves root device
     cat /proc/cmdline
  • Check correct fs recognition
    •   /lib/udev/vol_id -t /dev/sda1
        fstype /dev/sda1
      If the output of aboves command differ, your partition was not cleanly formated. For example mkfs.ext2 does not clear all sectors when formating a partition.
  • Check if the ata/ide/scsi driver is loaded
    •    cat /proc/modules
