Title:
  grub doesn't find boot

Status in GRand Unified Bootloader:
  Unknown
Status in “grub2” package in Ubuntu:
  Fix Released

Bug description:
  After a fresh installation of ubuntu (ubuntu-12.04-beta2-dvd-amd64) grub doesn't find the boot partition.
  grub runs rescue with error: invalid sector size 65535 (maybe grub tries to use a card-reader slot...)
  After
  sett prefix=(hd4,2)/ boot/grub
  set root=(hd4,2)
  insmod normal
  normal
  the system starts correct.
  See attached picture.

  Standard installation (on one hard disc) causes the same error.
  Installation using mbr causes the same error.
  Installation using gpt causes the same error.
  Disabling efi and using normal bios causes 12.04 to start in non-grafics mode.
  Best regards
  Mike
