So I finally decided to upgrade to windows 10 and the upgrade went smoothly. I went into device manager to make sure everything was fine, but it wasn't. I reealised my 860m was not showing up. Then i realized I just had to uninstall my old display driver and then install a windows 10 one which i got from geforce.com. In the installer it just said it could not detect compatabile hardwarwe. It is about a 2-3 year old Alienware latptop from dell.
