I upgraded to XP Pro and all went well, I have a hewlett packard 9110i cd writer and for some odd reason XP will not recognize that the drive even exists but it shows in BIOS ? I spent over an hour on the phone with HP techs and had no luck, where they redirected me to my PC manf. I took my PC to the local (custom) manf. and they charged me $40 for nothing as they couldnt figure it out either. Suggesting it a bad cd writer and that I buy a new one from them. I know the cd writer is problem free and worked perfect under win98 SE. can anyone please offer a solution ?
