Hi, My HP Pavilion originally came with Win7 on it. I just got a new hard drive for it and I want to install XP on it. From what I am reading this laptop was not designed for XP and when I try to install XP it starts but then throws a blue screen with the "stop: 0x0000007B" error. If this is related to if not recognizing the hard drive I'm kind of stuck because my laptop has the insyde H20 bios that do not allow changes for the XP install to recognize it. Are there modified bios that will let me install it? Thanks.
