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

[ZeroBeat]

Hi Larry.
I think ist's in the combination: efi + grub2 in ubuntu 12.04.
If i connect another usb-storage device bevor booting the system, harddisks change from hd4 to hd5.
grub2 doesn't recognise this change and looks for boot device on hd0.
ubuntu 11.10 works fine, using the same efi config.
Im using the following components:
asus P9X79 (asus-efi enabled)
samsung 830series (ssd) as boot
wd 2 TB as home
interal 4 x cardreader connected to the internal usb-port
Best regards Mike

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
