The same thing happened to me a minute ago. I was checking my mail and all by itself it rebooted with a black screen saying missing operating system on my pc windows 7. Is it a virus and if so why didn't Norton's antivirus pick up on it? Can someone please help!
i was on the homepage and all of a sudden it just restarted on its own and came back up to the screen saying missing operating system. I tried putting in the backup cd. I put in the windows 7 disk and tried to repair, it tells me to remove any removable items such as cameras and music players(which none were installed) I then tried to reinstall windows 7 and when it gets to the point of restarting it goes back to the same message of missing operating system.
