I'm reformatting and reinstalling my OS's on my hard drives and am having trouble getting rid of GRUB. My first hard drive is completely unpartitioned and empty, but it still has GRUB while my 2nd hard drive just has an NTFS partition taking up most it (the rest of it is unpartitioned). When I start up I am dumped to a GRUB prompt and can't figure out how to get rid of it. I've tried booting with the Windows XP CD in the CD-ROM drive but I am still dumped at the GRUB prompt. What can I do to purge my hard drive of GRUB and reinstall Windows XP?

GRUB resides on the MBR, which Winblows does not actually write to.

The best way to purge the MBR is to boot from a DOS / Windows 98 or ME floppy and do a "fdisk /mbr" command.

This will clear the MBR, so the computer will boot the active partition instead.
