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

[Michael Tsikerdekis]

@robert-tindall I think you are definitely on to something. Your
suggestions did help although my circumstances differed.

I was running 14.04 with a downgraded version of grub due to this issue.
I decided to go ahead and do a dist-upgrade. After that I would this
error msg that everyone has been having (so basically no boot menu, no
options whatsover just straight to grub_rescue).

My laptop is a VAIO and does have EFI. Multiple restarts would still get
me to grub_rescue. Then I decided to use the assist button and select
load from USB (but I had no USB inserted). I got "Operation system not
found!". Then I turned off my computer, turned it on again and suddenly
grub menu worked!!!

I got into ubuntu and I tried to dpgk-reconfigure grub-pc only to find
out that grub-pc was not installed and grub-efi was instead installed in
its place. So, I did a apt-get install grub-pc and it automatically
removed the grub-efi and install grub-pc.

Now, when I restarted everything worked fine BUT the moment I entered
windows and then restarted my computer again, I got the beautiful
grub_rescue screen. I bypassed it by using the asist button, booting
through a USB that does not exist and restarting.

>From what I've seen, grub-pc or grub-efi doesn't make a difference on
the result. But,  loading windows affects things. There is something
that happens when loading windows in my case at least that forces ubuntu
afterward to look for grub at the wrong place.

Any ideas on what may be the issue? I suspect that somehow MBR is
affected by Windows but in an UEFI computer I am not sure how that may
be,

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

Status in “grub2” package in Ubuntu:
  Triaged

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"
