Hello. If your computer has a windows XP Pro sticker on it you may be able to call Microsoft and validate your operating system if it is ligitamate, or buy an operating system disk on ebay for your brand of computer. Any Dell XP Pro disk will work with a Dell computer having a Dell XP Pro sticker, and so on for other brands, as long as your sticker has your computer brand on it. If you have a sticker without a brand name or no sticker at all you'll probably have to buy a retail disk.

These directions may be helpfull.
