[Bug 1341618] Re: grub 1.99-21ubuntu3.15 will not boot on some hardware

[Colin Watson]

There's not much of a hint here as to how far GRUB might have got, which
makes it rather difficult to guess at the problem.  Were there any
visual clues at all?

Can you try re-upgrading, working out what the usual grub-install
invocation is, adding --debug-image=all to it, then rebooting and seeing
what the last screenful of output is?

Title:
  grub 1.99-21ubuntu3.15 will not boot on some hardware

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  A production system of ours recently experienced the problem detailed
  in http://serverfault.com/questions/611423/did-grub-updating-bring-my-
  server-down but with grub-pc instead of EFI.

  Basically after upgrading to 1.99-21ubuntu3.15 one of our 12.04
  machines rebooted, and didn't survive the trip.  We struggled for a
  long time with a rescue USB key, and ultimately had to mount the
  filesystems in a chroot and downgrade to 1.99-21ubuntu3.14 (which
  solved everything).

  We've put the grub packages on hold on this system, but we're nervous
  about the ability for our 12.04 servers to survive a reboot just now.
  This has caused an extended service outage for an office full of
  people.
