Well, it didn't even asked me to press any key to boot from CD, I think I've missed a step in the process, I don't have the diagnostic diskette and yes the hard drive it's partitioned and formated, I had to use Win98 and WinXP, at one point the computer says that no version of windows it's found so I have to use any other version and after that it asked again for the WinXP, the reason I decided to wipe the hard drive clean and reinstall was due to a virus (according to someone that knows way much about computers than me) I've done it before when I had a Win 98 based computer but XP it's different. I'm starting to think that maybe it's the WindowsXP CD ROM the one with errors.
