Uninstalling rh 7.3

["Nigel Jackson" <nigelj pobox com>]

Hi all,

I'm a complete newbie & need some help here...

I need to uninstall rh 7.3 from an old machine...I thought I'd be able to
boot to a DOS floppy, then use fdisk to reformat the drive...but no!

Whatever I do I can't stop the machine booting to GRUB...even when I change
the bios to boot from the a drive, it still boots to GRUB.

What should I be doing here?
