I've attached both the disk and volume views from Disk Management as well as a view from the AOMEI tool since it also displays the MSR partition that's invisible to Disk Management. There's also a screenshot showing the legacy EFI "directory" on the boot drive that was previously used when the disk was MBR. This selection will no longer boot, but it shows up in the boot manager menu. It also seems to randomly shuffle the order of that boot menu any time I make a change to the BIOS. Even if I disable the boot entry for the MBR\EFI selection in UEFI, it still appears as an option during boot. This is what really drives me crazy since I can't tell which is the GPT/EFI and which is the MBR/EFI without attempting to boot. As a point of clarification, I intend to wipe the 850 to use as a single partition data drive once the 970 and BIOS are fully stable - so don't worry about its entries. (The diskpart command output is at the bottom of this post.)
