First check for all the Win XP drivers for your hardware.
You can check your HP/compaq PC here:
General XP Downgrade Guide for HP Laptops - HP Support Forum
NOTE: Please read this thread fully.


If your Win XP CD, does not support your Sata Controller, you will need to load drivers to uses at F6.
Load Sata Controller drivers with a floppy disk is the best way.

Do you have Windows 7 Ultimate? If so, you can download XP mode for free from Microsoft. It will allow you to run Windows XP and associated software within Windows 7.
