Adam, so far there have been two variations on the problem presented: 1) You are booting in bios mode with grub-pc, and grub- pc/install_devices is not set, which results in the MBR not being reinstalled on upgrade. There are systems on which this is a perfectly valid configuration ( i.e. if they are booting using another boot loader, or grub installed in another OS ), so we can't stop the upgrade for this.
2) You are booting in EFI mode with grub-efi, and have used boot-repair at some point which made a copy of grub.efi in the windows efi directory, and configured windows to chain load that. After upgrade, this copy is now old and broken because we don't know anything about it and it shouldn't be there. Grub-repair shouldn't be doing this. Fortunately this one is quite easy to work around: tell your efi bios to boot grub instead of windows first. -- 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
