This happened to me when upgrading from 13.10 to 14.04. I did not have any special Grub settings as far as I know.
I was unable to manually boot from the Grub rescue prompt as it could not read the partition filesystems (said they were msdos while they are ext). I tried the recommended solution from comment #39, i.e. run Boot-repair from a live USB, but when it wanted to reinstall Grub from a chroot on the broken partition it failed because I also suffered this bug from the same upgrade: https://bugs.launchpad.net/ubuntu/+source/gnome-settings- daemon/+bug/1286404 . Running "dpkg-reconfigure grub-pc" from a chroot on the broken partition using a live USB (Ubuntu GNOME 13.10 if I remember correctly) fixed the problem for me. -- 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/+source/grub2/+bug/1289977/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
