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

[Teo]

Ok, so I followed all of the steps in comment 169 (after having kind of
a hard time decyphering some of them) and it worked! I can now boot both
Ubuntu and Windows 8.

Now I WONDER whether the whole process was really needed. I SUSPECT it could all be reduced to (starting from the very beginning when everything was screwed up and the computer wouldn't boot):
- change the boot order from bios and place ubuntu before Windows
- then maybe the working grub menu would appear and you could boot ubuntu already
- run boot repair once with the "restore efi backups" option (this means: unfolding the "advanced options", checking the checkbox with this name, leave everything else as is, and click "Apply", and then follow all BootRepair's instructions until the end).

This is just a conjecture, but it would be nice to know whether this is
the case.

One thing I don't understand (whether or not the conjecture is right)
is: how comes that Windows bootloader had always been before ubuntu in
the bios boot order, and everything worked, and after the upgrade, among
other things, we needed to change that order?

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

Status in “grub2” package in Ubuntu:
  Confirmed

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"
