Title:
  After unclean shutdown, grub2 (grub-pc) fails until a keyboard is
  plugged in.

Status in “grub2” package in Ubuntu:
  New

Bug description:
  Binary package hint: grub-pc

  We are having some problems with grub2 (grub-pc) as it is installed by
  default in Karmic. This is running on a robot that does not usually
  have a keyboard attached.

  Here are the steps that cause the problem for us:

  1) Boot the computer.
  2) Do a hard shut down (flick the power switch).
  3) Turn the computer back on with no keyboard/mouse connected.
  4) Grub prints "GRUB Loading." and hangs forever.
  5) Reboot as many times as you like, no change.
  6) Plug in a USB keyboard and reboot.
  7) The system boots fine.
  8) Unplug the keyboard and reboot.
  9) The system still boots fine.

  This seems to be an interaction between having no keyboard plugged in,
  and having an unclean root partition. I had a quick glance at the
  code, and saw no obvious interaction. I tried using grub1 (grub
  package), and the problem went away, so that's what we are doing now.
  But there is something here that needs fixing.
