@robert-tindall I think you are definitely on to something. Your suggestions did help although my circumstances differed.
I was running 14.04 with a downgraded version of grub due to this issue. I decided to go ahead and do a dist-upgrade. After that I would this error msg that everyone has been having (so basically no boot menu, no options whatsover just straight to grub_rescue). My laptop is a VAIO and does have EFI. Multiple restarts would still get me to grub_rescue. Then I decided to use the assist button and select load from USB (but I had no USB inserted). I got "Operation system not found!". Then I turned off my computer, turned it on again and suddenly grub menu worked!!! I got into ubuntu and I tried to dpgk-reconfigure grub-pc only to find out that grub-pc was not installed and grub-efi was instead installed in its place. So, I did a apt-get install grub-pc and it automatically removed the grub-efi and install grub-pc. Now, when I restarted everything worked fine BUT the moment I entered windows and then restarted my computer again, I got the beautiful grub_rescue screen. I bypassed it by using the asist button, booting through a USB that does not exist and restarting. >From what I've seen, grub-pc or grub-efi doesn't make a difference on the result. But, loading windows affects things. There is something that happens when loading windows in my case at least that forces ubuntu afterward to look for grub at the wrong place. Any ideas on what may be the issue? I suspect that somehow MBR is affected by Windows but in an UEFI computer I am not sure how that may be, -- 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
