Windows

Hello,

You may have a boot sector virus. At my bench I would remove your hard drive and install it on one of my towers and run a virus scan on your hard drive. Recovery from a boot sector virus is very difficult using tools found in Hiren's Boot disc, a cdrom that contain various programs to recover a hard drive.

Lastly, you may simply have lost the boot strap loader (even though this doesn't make any sense if you have used your recovery CD and recovery partition with success. If you boot and hear a beep, press F8 repeatedly immediately after the beep and you'll receive the recovery bootup option screen, choose Safe Mode first and see if that works, if not choose last know good configuration and otherwise if offerred choose use System Restore.

If all this fails you as a user you need service from a professional.

Hope this has helped or fixed ya.
