[Bug 975061] Re: grub doesn't find boot

[quequotion]

This bug should have a very high priority.

It is a known bug in GRUB and it is already fixed upstream:
http://savannah.gnu.org/bugs/?35382

This bug prevents (U)EFI systems from booting.

If you know grub really well, and your partition layout really well, you
can manually specify all the parameters and commands necessary to boot
at the rescue prompt starting with the "prefix" which is probably set to
the wrong drive.

Please package the upstream fix for ubuntu before this disasterous bug
gets into the wild!

Title:
  grub doesn't find boot

Status in “grub2” package in Ubuntu:
  Confirmed

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
