Do you want to recover XP right now - boot from the Xp CD and run Repair install, not the first "R" given but after it discovers the installation it will offer it again.
Or do you want to install Win7? Google your model to find mobo, then google mobo + sata driver and track it down.
You need to check your model's Support Downloads page for BIOS update. Tap F-key given at bootup to enter Setup and look for BIOS version to see if you need an update.
