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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1289977 Title: Ubuntu 14.04 Update breaks grub, resulting in "error: symbol 'grub_term_highlight_color' not found" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-upgrader/+bug/1289977/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
