      The past few days have been very stressful for me – somehow my computer got stuck at a “Grub Rescue” prompt whenever I would reboot.

      I tried running the Grub Rescue commands to find my Linux partition, setting it to Root, running “insmod normal” and “normal”, but that didn’t work, because apparently there was no Grub folder. (I couldn’t find it.)

      I tried booting to Linux Live, mounting my hard drive Linux partition as the active one, then running “grub-install”, but that didn’t work. But this step made some progress – I now rebooted to a “Grub” prompt rather than a “Grub Rescue” prompt.

      I even tried copying the Grub folder (and all subfolders) from the Linux Live DVD to my hard drive, but that didn’t work.

      I found all of the above suggestions by searching the web. I don’t remember the specific locations, except that one of them was a Youtube video.

      What finally fixed it was a procedure I found at

      Basically, I ran a few commands from a terminal window, then a command called “boot-repair”. Once boot-repair finished running, I removed the Linux Live DVD and rebooted.

      Here’s what HowToGeek says about Boot Repair: “Boot Repair is a graphical tool that can repair GRUB2 with a single click. This is the ideal solution to boot problems for most users.”

      It worked for me, and it will probably work for you if you ever get stuck at a grub or grub rescue prompt.

      Here are the steps to follow, as outlined in the HowToGeek article:

      1. Boot to Linux Live, either with a DVD or a flash drive.

      2. Make sure you have a good internet connection.

      3. Open a Terminal window and run the following commands to install and launch Boot Repair:

      sudo apt-add-repository ppa:yannubuntu/boot-repair

      sudo apt-get update

      sudo apt-get install -y boot-repair


      4. Follow all on-screen instructions in Boot Repair; choose “Recommended Repair” when asked.

      Once Boot Repair finished, I removed the Linux Live DVD and rebooted. The Grub boot menu appeared for a few seconds, and then I came to the login screen for Linux Mint.

      Problem solved!

      BTW – computers with either buggy UEFI firmware or dead CMOS battery (or both) may end up at a Grub Rescue prompt on their own too.

      Say, one of those models that by default looks for Windows by name… specifics vary but at least one of these models will boot up just fine after exiting the Grub Rescue interface and then picking the UEFI-mode internal disk out of the firmware menu it drops to.

      A partition restore would have done the same thing only faster.

      cheers, Paul

      Hello! I am replying to this thread even though it is a couple of weeks old. I have run into a GRUB repair problem and in my search came across this thread. I started a post about it, GRUB boot issue and Macrium Backup but thought I’d also post here.

      After reading through this post and thinking a bit more, I think the issue for me is that the boot loader on my Windows 7 laptop has been somehow compromised during the attempt to install Linux Mint on an external SSD. When I initially tried to boot into that SSD drive after the Mint install, I got the GRUB repair message, but I think that was because the GRUB in Windows wasn’t working. I can access Windows using my Mint install on my thumb drive – there I get a choice, but I think that is because the GRUB on the thumb drive is working. Before, if I wasn’t booting into the thumb drive, it would go right to Windows – now I can only access Windows through that USB thumb drive’s GRUB menu.

      I know this is the Linux forum, but I was wondering if the process of repairing that you used would also be able to repair my Windows GRUB as well, since I think that is where the problem lies. No idea why it would have gotten changed when I was dealing with my YUMI drive and installing Mint on the SSD.

      Anyway – took a chance posting here to see if this process might repair the Windows GRUB as well.

        Lily, we are dealing with it in your original thread. Easier than moving it across multiple threads.

        cheers, Paul
