If I was running Windows 10 in a Virtual Environment, I could not use my GTX 680 2GB GPU for graphics, and I would have a Virtual Hard drive with the OS installed on it.

By the way, did you look at the link I provided about Installing Windows?

I will gladly allow you to connect to my system using Teamviewer so you can show me how to verify that I am in a Virtual Environment... Maybe we can figure out this together..
