Ok, so I followed all of the steps in comment 169 (after having kind of a hard time decyphering some of them) and it worked! I can now boot both Ubuntu and Windows 8.
Now I WONDER whether the whole process was really needed. I SUSPECT it could all be reduced to (starting from the very beginning when everything was screwed up and the computer wouldn't boot): - change the boot order from bios and place ubuntu before Windows - then maybe the working grub menu would appear and you could boot ubuntu already - run boot repair once with the "restore efi backups" option (this means: unfolding the "advanced options", checking the checkbox with this name, leave everything else as is, and click "Apply", and then follow all BootRepair's instructions until the end). This is just a conjecture, but it would be nice to know whether this is the case. One thing I don't understand (whether or not the conjecture is right) is: how comes that Windows bootloader had always been before ubuntu in the bios boot order, and everything worked, and after the upgrade, among other things, we needed to change that order? -- 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
