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

[arco444]

Had the exact same problem today. Upgraded from 13.10 to 14.04 this
morning and was greeted by:

symbol 'grub_term_highlight_color' not found

and the grub rescue prompt.

Supergrubdisk did not work for me, neither did the various other methods
mentioned above. I'm using 2 disks with LVM. /boot is located at sda1
and always has been. The rest of the OS is on the LVM partition which is
spread across other partitions on sda and sdb. No manual changes have
ever been made to grub since the system was built 7 months ago.

Solution was to manually load the kernel from the grub console

set root=(hd0,1)
linux /vmlinuz-3.13.x-xx-generic ro root=/dev/mapper/vg-root
initrd /initrd.img-3.13.x-xx-generic
boot

Once in the system, dpkg-reconfigure grub-pc had no effect. 
Had to first run grub-install --boot-directory=/boot -v --recheck /dev/sda

This brought back expected grub menu options at boot.

A subsequent run of "dpkg-reconfigure grub-pc" was then successful.

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

Status in Ubuntu Release Upgrader:
  New
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"
