A friend of mine has a Sony VAIO all in one computer. She had a virus on the machine and I installed Norton 360 on it. After the install I told Norton to check for updates. It said an hour wait, so I left, when I came back it stated "Missing Operating System". I went to the Recovery Wizard and pulled the files off the disk that she wanted. We then told the wizard to restore back to factory default. It said 100% and then said it needed to reboot. After the VAIO logo went off the screen on boot up, it went back to saying missing operating system. I have done this three times with the same result.
Anything else I can try?
Thanks for the help
