Operperating System not found on bootup
I have a Sony Vaio Laptop running Windows XP. All of the sudden when I boot it up it automaticly says Operating System not found. It will not boot just keeps saying the same thing with any buttom I hit. After turning it of and on a few times it will boot and run normal. Sometimes it takes clicking it off and on 10+ or more times before it boots up and I know that isn't a good thing to have be doing!
Anyone have any idea what has caues this? I have done a system restore and ran 2 different virus scans and adware/spyware programs.
Any ideas would be greatly appreciated.
