I am in the process of doing a clean install on our home desktop. I booted up the cpu, and I chose start from disk. It took me to Windows XP Home Edition Setup screen. It gives me three options, the first is to set up Windows XP now, and Press Enter. The second is to repair an installation, press R. The third is to quit. I obviously want the first one, and i so I press enter….but nothing happens. I checked the keyboard, and its plugged in and working. But it doesnt take me to the next screen. What can I do? Please help
