You may have started off the install incorrectly.
http://www.blackviper.com/Articles/OS/InstallXPPro/installxppro1.htm shows you don't format the drive with any DOS diskette.
I am having problems with installing software after formatting my 2nd pc. I keep getting a blue screen error when I try and install XP. I have change bios settings to default but this has not helped. I have disconnected 1 hard drive and changed them around but the problem still happens. I have run scan disk but it doesnt find any problem with the hard drive.
The PC is a 1.3 athlon with 512mb ram.
I am hoping a pc guru here can help me....
