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

[Palmar Thorsteinsson]

This happened to me when upgrading from 13.10 to 14.04.
I did not have any special Grub settings as far as I know.

I was unable to manually boot from the Grub rescue prompt as it could
not read the partition filesystems (said they were msdos while they are
ext).

I tried the recommended solution from comment #39, i.e. run Boot-repair
from a live USB, but when it wanted to reinstall Grub from a chroot on
the broken partition it failed because I also suffered this bug from the
same upgrade: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-
daemon/+bug/1286404 .

Running "dpkg-reconfigure grub-pc" from a chroot on the broken partition
using a live USB (Ubuntu GNOME 13.10 if I remember correctly) fixed the
problem for me.

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"
