I'm intrigued. Let me ask some simple questions...

How many physical hard drives do you have? Do you know if you have other logical drives?
Nothing else plugged in to the USB ports anywhere?
When you boot, do you get a choice of operating systems?
Did you leave the CD in the CD tray?
Is this a laptop?

Please respond and also explain how you reformat the drive.
