Hello, My hard drive on my windows xp professional computer recently crashed. I seeked help in the hardware section on techspot and figured out I had to buy a new hard drive. So I went out and bought a 500gb hard drive which is a big upgrade from the default 80 that it came with. Unfortunately I dont have any xp disk. Fortunately I have a sticker on the side of my computer with my old xp pro product key. It says Windows XP Professional OEM Software then it has the product key. Is there any way to get widows xp back onto my pc with the new hard drive with my old product key. P.s. I have some hp xp recovery disks because my family has my hp pc's with xp but this computer isnt hp would that put xp back on it?
