I've just removed a distribution of Linux from my laptop which was dual booting with XP SP2 RC2. When I've done this in the past (before putting SP2 on) I've got rid of the GRUB loader by sticking the XP CD in and running FIXMBR and/or FIXBOOT from the Repair Console.

Trying to do the same now won't work because the setup program detects the later version and refuses to start. I've tried using the SP1 setup, with the same result and I don't have SP2RC2 setup files available.

Any way of restoring the original MBR, without having to re-download the RC2 files?
