Get a genuine Windows disk. Boot the pc with it. Delete and recreate any
partitions and then reinstall the OS. Note - what you now have will be
gone.

That doesn't matter. Nothing important is on it that wasn't saved in a
thumbdrive.

Also note - I have two older Dells will not install Win7 for some reason
(just reboots and starts over) but they do install XP with no problem.
