[wireguy 0]

I have win2k pro and I recently installed a driver for my printer

and restarted my computer and now all I get is a plain blue screen with no text. I tried to boot in safe mode but in safe mode all I get is "safe mode" in all 4 corners on a black screen with no icons. I've tried last known good configuration but still get the plain blue screen. I do not have a win2k pro disk of any kind. Please can anybody help me!
