fixmbr - Repair Windows XP Master Boot Record

I happened to hose my MBR which pointed to a GRUB (boot loader for Linux) while uninstalling all Linux OS-es from a Laptop. In the process, the Windows boot records also got deleted, and the machine lay sans a valid boot-loader. Eventually the only OS that I was interested in having on this laptop was Win-XP.

To install a fresh new Win-XP (actually Win NT) boot-loader
  1. B from the Win-XP installation
  2. Enter the "Repair" mode and find your way to the DOS prompt
  3. Type in the fixmbr command, and let it replace the MBR completely
  4. Exit and reboot
