Angels have the Phone Box
Guys, I think the best thing to do here, is disconnect all drives but the one SSD that we want W10 on. Then, boot to the W10 install media and clean install W10 on it. Just get W10 on the machine to grab the digital license. Once that's done, we can worry about everything else. We're running out of time for the free upgrade. If we can't get W10 clean installed on the extra SSD because of hardware incompatibility or lack of drivers, then we won't have to spend time on the upgrade, you know?
