As pointed out by Peng (pengwg) at #2, this might be confirmed a bug of grub 2.02. I upgrade my 13.10 to 14.04 (grub was upgraded to grub~beta2~9), then I encountered this problem.
My machine is with UEFI. When I see this error, I restarted my computer and selected boot from UEFI file. Then I navigated to the ubuntu uefi file and started my computer successfully. I tried the simple "sudo grub-install --recheck /dev/sdX" way. But it didn't work. The I downgrade all the grub components: grub-common, grub2-common, grub-efi, grub-efi-amd64, grub-efi-amd64-bin to version 2.0. Rerun that "sudo grub-install --recheck /dev/sdX", restarted computer. Everything is back now. For me this owngrading of grub works. Possibly a bug with grub-install in the 2.02 verion. -- 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
