Public bug reported:
The update process to Oneiric reported that it was unable to update grub.
Now, the boot screen is just black with a blinking cursor, no traces of grub or
the kernel.

Reinstalling grub in chroot fails:
---
root@ubuntu:/# grub-install /dev/sda
/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: will not proceed with blocklists.
root@ubuntu:/# grub-install /dev/sda2
/usr/sbin/grub-setup: error: /dev/sda appears to contain a xfs filesystem which
isn't known to reserve space for DOS-style boot. Installing GRUB there could
result in FILESYSTEM DESTRUCTION if valuable data is overwritten by grub-setup
(--skip-fs-probe disables this check, use at your own risk).

Creating a new boot partition with ext2 yields the same grub message
about blocklists
