Solve : Reformat problems?

1.	Solve : Reformat problems?
Answer» I've been trying to reformat my friends computer, and it all goes well until setup finishes COPYING the files and it RESTARTS. Where it would NORMALLY GO through the windows gui, its starts the reformatting again. Ive tried taking the cd out but then i GET the "Operating system not found." any suggestions?what type of computer is it? What motherboard and processor? What operating system are you trying to install? Is it an original cd or a copy, and is it a full install or upgrade version?
