Hello wizards, I have an MSI Z170a Gaming 7 board updated to the latest BIOS. I've had my OS installed on a 500GB Samsung 850 Pro (SATA 3 Version) for a while, and since it's filling up fast, I recently purchased a Sandisk 400 1TB m.2 SSD. I used a hard drive dock with a m.2 to SATA adapter to clone the Samsung SSD to the Sandisk. The problem is, when I plug the m.2 SSD into the board, the BIOS (or OS) doesn't see the SATA SSD any longer. If I take the m.2 out, the SATA SSD shows up again. I'm not sure if there is some sort of issue with both drives having the same Windows 10 Pro key attached to them? I'd like to keep the SATA SSD the way it is for now, but I guess if it needs to be formatted to work I can do that. Any advice would be helpful. Thanks!
