Hello, My hard drive running windows XP on it started to fail so I got a new one and installed windows server 2008 as this machine is a server. So now I have two hard drives running two operating systems. I tried to format the old one and couldn't in windows so tryint to be clever I loaded up the OS disc and formatted the old one trough the OS setup and left my new one alone. Now I have sucessfully formatted my old HDD but now I cant boot from my new one and it says insert disc. I put yet another hard drive and loaded an os from that and its ok and I can still see files on it so I can backup but why cant I boot windows on it? Thank you.
