I had trouble with my first installation of ubuntu so I'm trying to uninstall everything so I can do a clean reinstall.

I've deleted the partition but the problem is that the grub bootloader is still on listed in the bios boot options.

I've tried using the remove boot option feature on the bios, EasyBCD, and EasyUEFI but the grub bootloader won't go away.


Parts of the bootloader are stored in the UEFI boot partition. For Ubuntu, this is only four files in a Ubuntu subdirectory:


So, if you can manage to mount to UEFI boot partition (for example using a bootable Ubuntu USB key, choosing "Try It", and using the terminal from there), you can remove the files.

But I suggest you do not bother: when you do you reinstall, the four files will quite simply be overwritten.

  • Can you elaborate on how to remove these files? – user633627 Dec 22 '16 at 6:46
  • In Ubuntu, you'd use the rm command. You should read up on mount points and basic Linux/Unix commands like rm. There are numerous online tutorials about these subjects. – Rod Smith Dec 22 '16 at 14:44

I think reinstalling the windows bootloader will automatically overwrite GRUB bootloader.

The procedure to reinstall windows bootloader is mentioned here.

However, I don't think that's required. You can simply proceed to reinstall ubuntu without doing so. That will be a clean Install.


I've developed a Windows app for solving the problem you have. It removes Grub and restores Windows Boot Manager. ONLY WORKS WITH EFI INSTALLATIONS!

You only have to download my application and execute it (in Windows). It's free!

Obviously you will need a Windows installation, this program is pointed to dualboot pc's.

If you only have Linux, reinstalling will overwrite the old GRUB!
