If you have the OS CD you can use the Repair Console and try this command. Boot from the CD and run this command:
This will fix the Master Boot Record.
This morning I somehow got the "System Restore" virus. It's the one
where it restricts many programs, claims to be Windows System Restore,
and tells you that you have a bunch of hard drive "Critical" errors.
Anyways, I did what I always do. I rebooted, entered safe mode w/
networking, and used Malwarebytes to get rid of the virus. Problem is
though, when I rebooted, and every time I have tried to turn my comp on
ever since, my computer stalls when trying to boot by the HDD. It never
gets to the Window's load screen. I don't know how I would have an HDD
faliure from cleaning a virus, but it's always possible. Any advice?
