Computer Won't Boot From Windows CD

[stopstartstall]

Bit of a weird problem, I tried to reinstall Windows XP the other day and the computer wouldn't boot from the cd. I had a linux disc to hand, so I tried that and it booted straight into it first time. I installed xubuntu, left it for a couple of days and then decided to retry the Windows disc. (I have a rather blase attitude to reinstalling OSes )

The windows CD still won't boot but linux live CDs work fine.

The Windows CD will boot in other computers - I tried it in an old laptop and got as far as "press any key blah blah..." so I know it will work.

I've tried putting a different hard drive into the computer and it still won't boot, so it's not a problem with the hdd.

Oh and the BIOS is set to boot from CD first

I'm completely stumped, anyone have any ideas?

I haven't got another Windows cd. I did give it a bit of a clean, and I even tried burning a copy cuz the cd is a bit scratched, but the copied version wouldn't boot either.

I have got another drive I could try, it just means pulling apart the media pc downstairs. Not sure if it is the drive though, cuz it will boot from other cds - just not this one. The cd can be read from within the OS as well, just not at boot apparently?
