[font="Calibri,Arial"]if your computer is under warranty, try your manufacturer. Otherwise consider downloading Linux/Win7 beta. I wouldn't use a pirated XP as aside from the ethical issues you will be unable to get updates for it and any MS software which could leave security holes in your system.[/font]
Assuming it was an OEM disc, contact your manufacturer. Even if you're not under warranty, you may be able to get them to send you a disc (this worked for my sister with Dell).
I have the product code for XP I just do not have the disc needed to reinstall it. Or well I can not find it in any of the places we keep out software.
And the computer is not under warranty. It is quite old.(updated but old.)
