[Bug 978464] Re: Upgrade 10.04 to 12.04 Beta 2 failed, grub issue

[Steve Langasek]

Whatever issue prevented the users from upgrading their MBR from 10.04
to 12.04 is unlikely to magically resolve itself for 12.10; so we should
really fix this for quantal as well.

Bug description:
  I upgraded a 10.04 to 12.04 Beta 2.

  After the compulsory reboot, I ended up stuck on a GRUB shell.

  GRUB didn't get properly updated

  Screen shot is attached.

  I know how to pass that problem manually by upgrading grub
  configuration by hand using a LiveCD.. But obviously, for your lambda
  users it's going to be a massive blocker.
