[Bug 972250] Re: "This GPT partition label has no BIOS Boot Partition"

[wces]

I too got this error today after upgrading to 12.04 from 11.10. My Grub
is installed on a partition and NOT in MBR. It worked perfectly fine in
11.10

These are my Grub related packages:

ii  grub-common                            1.99-20ubuntu1                          GRand Unified Bootloader (common files)
ii  grub-gfxpayload-lists                  0.5                                     GRUB gfxpayload blacklist
ii  grub-pc                                1.99-20ubuntu1                          GRand Unified Bootloader, version 2 (PC/BIOS version)
ii  grub-pc-bin                            1.99-20ubuntu1                          GRand Unified Bootloader, version 2 (PC/BIOS binaries)
ii  grub2-common                           1.99-20ubuntu1                          GRand Unified Bootloader (common files for version 2)

Title:
  "This GPT partition label has no BIOS Boot Partition"

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  On a system installed with 11.10 and upgraded to 12.04 last week,
  today grub fails to apt-get upgrade with this error in
  /var/log/apt/term.log:

  /usr/sbin/grub-setup: warn: This GPT partition label has no BIOS Boot Partition; embedding won't be possible!.
  /usr/sbin/grub-setup: warn: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
  /usr/sbin/grub-setup: error: non-sector-aligned data is found in the core file.

  The system has luks+lvm as installed by 11.10 alternative installation
  cd, and indeed seems to have GPT but no BIOS partition (system is
  running BIOS on Asus F1A75V-PRO motherboard).
