Ultimately I could probably sort this out on my own, but someone is bound to know the answer with some conviction. I have a lot on my plate today, so I'll just ask.
Typically, no disks that have come into my possession have a size greater than 2TB. So I haven't bothered to format them as GPT.
However, it IS possible (only to me at the moment, given my sketchy knowledge) that Windows might automatically choose GPT. But it never did with Windows 7. I'd only seen this happen with Windows 10. GPT has more "small partitions" or volumes than just "System Reserved."
Is this in any way tied to Windows "booting in UEFI mode?" In other words, if I made an initial mistake in preparing to install windows, the drive was already initialized for MBR and my installation left me with just "System Reserved" and a "C:" volume, did I screw up "booting in UEFI mode?"
Or am I "good to go?"
One reason this question has my attention: I'm planning to clone my Win7-64-SP1 "Pro" installation to a 950 Pro Samsung M.2 card. I'd like to avoid detours and troubles. I'm pretty sure I have to set BIOS to "M.2 mode" as opposed to "PCI Express."
