what you can do is get some drive clone software, and clone it to the SSD, unplug the SATA & power from the old drive, and have only the SSD hooked up, the system will automatically boot to the cloned drive. replug the 1TB SSHD and format the windows partition and merge the windows partition with the storage partition so it's one instead of the weird split. that's how i did it with my Samsung 850 evo 500gb SSD and the G20AJ-US009S's 1TB SSHD.
