Currently have Windows 7 Ultimate 64bit installed on my Kingston HyperX 3K SSD. I just bought a SAMSUNG 840 EVO and want to use that as my W7 drive and my Kingston as just a storage drive for games etc... I'm not 100% sure how to go about this. I initially just unplugged my Kingston SATA cable and started my pc with only the Samsung drive running and instantly installed W7 on it. It got to the very end and I went to input my product key in and it said "This product key is not valid". I then went ahead and shut it all off and started it up with the Samsung unplugged and the Kingston plugged into come research. Do I have to somehow deactivate W7 on my Kingston drive or reformat this SSD? I've searched around a bit and kind find a straight "Noob friendly" answer. I don't see how I can reformat my current drive with it running W7
