I just bought a computer from a guy online, who deleted windows xp off the computer to run linux, and before he sold it took that off as well. He has the original disk and COA. He didnt install XP back on it for me 
He told me that to install XP, put disk in, when it starts up, and says "press any key to boot from disk".... to push any key. When it says press any key to boot from cd, it has dots... that appear until i push a key, then they stop coming, and the cd makes some clicking noises like its reading, followed by a whirring noise like its booting uo. But then it does nothing. The whirring subsides and it stays at the push any key to boot from cd screen. Any ideas? I need to get this installed before my cable modem guy comes to install today. Could the disk be bad? It is scratched on the bottom and on the top there is (2) 2-3mm parts where the cd lavel is scratched off, like you can see the disk. The guy said that it doesnt matter because the label is only need to create the disk, and not to read it. I dont buy it. Any ideas?
