|what do you mean by xp2?|
do you mean windows xp service pack 2?
what happens when you try to install it?
i would assume you get an error which says it cannot find your hard drive? again i assume your hard drive is SATA, windows xp does not natively support sata drives so you will need to install the drivers for it during install, press the F6 button when prompted.
or use something like nlite to produce a bootable cd to with the drivers slipstreamed into it.
