[Bug 1289977] Re: Ubuntu 14.04 Update breaks grub, resulting in "error: symbol 'grub_term_highlight_color' not found"

[Phillip Susi]

Adam, so far there have been two variations on the problem presented:

1)  You are booting in bios mode with grub-pc, and grub-
pc/install_devices is not set, which results in the MBR not being
reinstalled on upgrade.  There are systems on which this is a perfectly
valid configuration ( i.e. if they are booting using another boot
loader, or grub installed in another OS ), so we can't stop the upgrade
for this.

2)  You are booting in EFI mode with grub-efi, and have used boot-repair
at some point which made a copy of grub.efi in the windows efi
directory, and configured windows to chain load that.  After upgrade,
this copy is now old and broken because we don't know anything about it
and it shouldn't be there.  Grub-repair shouldn't be doing this.
Fortunately this one is quite easy to work around: tell your efi bios to
boot grub instead of windows first.

Title:
  Ubuntu 14.04 Update breaks grub, resulting in "error: symbol
  'grub_term_highlight_color' not found"

Bug description:
  The update from 13.10 to 14.04 via update-manager broke grub for me,
  which resulted in the grub error:

  "symbol 'grub_term_highlight_color' not found"

  on startup.

  To fix the problem I had to boot to my persisting Ubuntu installation
  (e.g. using Super Grub Disk) and had to reinstall grub on my boot
  partition: "sudo grub-install --recheck /dev/sdx"
