Let me ask a little more clearly. This is my plan. I need to get a bootable usb ready with windows ISO, backup my current HDD, Swap out the HDD for the SSD, Boot with USB, install Windows 8 on the SSD, move game files to SSD. But at this point i would want to reinstall my old HDD for the extra storage space. My concern is that the HDD is still formatted with windows 8.
