Title:
  grub failed to update on Natty

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub

  My last Natty update was few days ago.
  I just updated my (previously) working Natty on MacBook Pro and the process was stuck during the grub update (the last lines displayed were the list of kernel found and memtest86).
  Ctrl+C helped to stop the update but grub and new kernel 2.6.38-8 packages installation were not finished.
  dpkg --configure -a was stuck too.

  A reboot was a bad idea because grub doesn't load.

  I managed to boot on a livecd and chroot.
  dpkg --configure -a helped me finish the installation but grub displayed "This GPT partition label has no BIOS Boot Partition...".

  I am now stuck because grub is not loading at boot and it won't
  reinstall (same GPT BBT error).

  Is there any manual way to revert to a working boot/BBP/grub?

  Thanks.
