Title:
  Latest update renders system unbootable "error: no such partition"

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  Just did my daily 12.04 updates and ended up with an unbootable
  system:-

  error: no such partition.
  error: no such partition.
  error: no such partition.

  Press any key to continue...

  I had to chroot into the install to reinstall grub and the kernel to
  get it back to a bootable state.

  See attached photos.
