GRUB rescue problem after deleting linux partition

After I deleted my Ubuntu partition, I rebooted my computer and I only get a prompt:

grub rescue >

Try the following .. grub rescue > ls (hd0) (hd0,msdos5) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1) (hd1) (hd1,msdos1) grub rescue > ls (hd0,msdos1) # try to recognize which partition is this grub rescue > ls (hd0,msdos2) # let's assume this is the linux partition grub rescue > set root=(hd0,msdos2) grub rescue > set prefix=(hd0,msdos2)/boot/grub # or wherever grub is installed grub rescue > insmod normal # if this produced an error, reset root and prefix to something else .. grub rescue > normal For a permanent fix run the following after you successfully boot: sudo update-grub sudo grub-install /dev/sdX where /dev/sdX is your boot drive. OR up vote down vote I had the same problem. I removed GRUB. Just download Windows 8 or 10 from another PC. Burn the iso into the USB with Rufus. Boot from USB, click Troubleshooting, then Command Prompt, and type: Bootrec /fixmbr Windows will start normally without Ubuntu's GRUB. You can reinstall Ubuntu again.
