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

[RJ White]

Folks,
I was bit by this today, turning my dual-bootable laptop into a brick.
I tried a lot of things here and nothing worked.
What did work for me was following directions in http://community.linuxmint.com/tutorial/view/245
I'm running Linux Mint 17 Qiana, which is based on Ubuntu 14.04
I was upgrading from Mint 16 to Mint 17 and the install appeared to work fine.

For me, the following worked:

             mount /dev/sda5 /mnt
             grub-install  --root-directory=/mnt/  /dev/sda
             reboot

which is close to some suggestions others made but those didn't work for me.
Obviously you'd need to change the sda5 to whatever is appropriate for you.
No, I have not made a typo above.  There is no trailing number on the sda for the grub-install command.

The above for me worked, despite the error message:
          "grub-probe: error: failed to get canonical path of /cow."
Hope this helps.

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"
