I recently uninstalled Ubuntu after having dual-booted Ubuntu and Windows. Now when I boot normally, I reach a screen that simply gives me a grub prompt. I can get to Windows by booting, pressing F11, and selecting "Windows Bootloader", but I would prefer to be able to go straight to Windows.

Per the answer here, I tried running bootrec /fixboot and bootrec /fixmbr in succession, which had no effect.

I then backed up my system on an external drive and attempted to reinstall from that, but I was unable to do so because "the system image was created with UEFI" instead of BIOS.

Thoughts/suggestions?

  • Did you execute the bootrec commads on a recovery disk on in the installed windows system? Note there are other similar questions such as this which have other options. – Wilf Jan 28 '15 at 00:18

  • It sounds like you have a UEFI computer so running bootrec /fixmbr won't help (that installs the windows bootloader to the master boot record). Instead you should go into your 'BIOS' settings (F2 at boot or lookup in manual) and set Windows as the default OS to boot. – bcbc Jan 28 '15 at 03:13

This technically might not be uninstalling GRUB, but it produced the desired behavior (i.e., booting to Windows instead of GRUB). Here's what I did:

  1. Open cmd.exe with administrator privileges
  2. Run bcdboot C:\Windows, replacing C with the appropriate drive as necessary

That was it!
