I cannot install win xp on my hp pavalion

Hello

the easiest way out is to change the bios settings so that the disk is running in native mode, search for that settings in bios then the windows XP installation should find your disks.

other way is to have a Disk drive and download the sata driver from the manufactory site.

third way is to make a new xp installation cd with the new driver.

but try the first one first. little more info about your computer should be helping me to help your more?

good luck
