Title:
  GRUB hangs if a disk is connected

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  I have a Gigabyte G33M-DS2R (Core2Duo) system currently running
  10.04.4. I tried to boot a 12.04.1 (amd64 server) ISO and it hangs
  unless I unplug the disk so the BIOS doesn't see it.

  If I unplug the disk, then plug it while the kernel loads I can
  install onto it but rebooting onto it hangs.

  I see absolutely no debugging information though - the last message on
  the screen is "Updating DMI Pool Data ...." which is from the BIOS.

  I tried holding down shift as well as tapping escape while GRUB starts
  but I didn't get given a menu.

  Ctrl-alt-del does reset the PC so presume that it must happen very
  early on.
