This is my first post and I really need help. I recently uninstalled Deepin for Ubuntu 19.10 and I think uninstalling also messed up grub and I am stuck with grub rescue. Can you tell me how to fix it. I’ve looked through many articles and forums but none of them help

    What is "Deepin for Ubuntu 19.10"?

  • This didn't make anything clearer. If you uninstalled some other distro, it is expected that you can't boot to it. Now go ahead and install Ubuntu if you like. So what is the question?

  • I know I can’t boot to a district I uninstalled. I mean Ubuntu installs properly but grub can boot to Ubuntu because it is messed up somehow

  • Then you did not install grub correctly, to drive that you boot from. So it still is using old grub from old install. May be best to see details, use ppa version with your live installer (2nd option) or any working install, not older Boot-Repair ISO: Please copy & paste link to the Boot-info summary report ( do not post report), the auto fix sometimes can create more issues. help.ubuntu.com/community/Boot-Repair

Boot with a live USB, select "Try before installing", open a terminal with Ctrl+Alt+T and install boot-repair:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

Then type boot-repair and a menu will appear:

Select the recommended option.

If your system boots normally after recommended repair great. If not post the link to the problems reported.

On some systems this annoyance can occur:

  • Thanks, I figured it out on my own, but while I was trying to fix it, boot repair said it had missing dependencies. could you explain that? Thanks

  • @TheBuntuNewb I'm afraid I've never seen missing dependencies in boot-repair. Dec 15, 2019 at 20:08
