This is becoming less relevant as new systems all have UEFI, but if you want to remove GRUB from a system with BIOS, here’s how to do it.

  1. Boot into Windows or Windows recovery disk
  2. Assuming disk with GRUB is C:\, run the following from an elevated command prompt:
     bootsect /nt60 C: /mbr
    

    This will update the Master Boot Record of the drive without affecting the partition table.
