Folks, I was bit by this today, turning my dual-bootable laptop into a brick. I tried a lot of things here and nothing worked. What did work for me was following directions in http://community.linuxmint.com/tutorial/view/245 I'm running Linux Mint 17 Qiana, which is based on Ubuntu 14.04 I was upgrading from Mint 16 to Mint 17 and the install appeared to work fine.
For me, the following worked: mount /dev/sda5 /mnt grub-install --root-directory=/mnt/ /dev/sda reboot which is close to some suggestions others made but those didn't work for me. Obviously you'd need to change the sda5 to whatever is appropriate for you. No, I have not made a typo above. There is no trailing number on the sda for the grub-install command. The above for me worked, despite the error message: "grub-probe: error: failed to get canonical path of /cow." Hope this helps. -- 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
