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

[Colin S.]

I too experienced this bug: my perfectly-functional Ubuntu 13.10
(x86_64) system was rendered unbootable on upgrade to 14.04 with the
grub "grub_term_highlight_color" error. My computer has two disk drives:
one with Windows 8 and one with Ubuntu. I use GPT/EFI exclusively, with
secure boot turned off. My EFI partition was formerly located on the
Windows 8 drive.

To fix this problem, I created an empty EFI partition on my Ubuntu disk
and installed rEFInd from its installer script. It appears that my
motherboard's EFI does not remember NVRAM settings for symbolic names
like "ubuntu" or "refind": it only remembers which device (i.e., disk)
from which it should boot. In order to make refind work, I had to
install it from its install script [1] as

   ./install.sh --usedefault /dev/sdXX

which makes refind the device default for the disk on which it is
installed. Caution: read the install script's manual carefully first!
Now I can boot both OSs.

I am not sure if this is the correct solution, but it helped me. If your
system has been rendered unbootable in this state, Super Grub Disk can
get you back into your OS so you can make these changes.

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"
