Re-install Windows or use the factory recovery process. If Windows will not install or factory recovery doesn't work, the hard drive may have failed. Test it with the manufacturer's diagnostic software for DOS which loads from a bootable CD. The download links are here: http://www.tacktech.com/display.cfm?ttid=287

I guess the only is os re-install. You can save all necessary data to make boot with bootable device
