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

[Tomi Pieviläinen]

I should also add that the system has booted up fine since the upgrade
to precise, but haven't tested it today after the error.

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).
