Some systems will only boot a NVMe device via UEFI.

Edit: Am I also mistaken in thinking that to boot off an NVMe SSD, one must
have UEFI turned on??

This is not true at all. Never used UEFI here and have installed Win
10 several times.

That is very bad news. I was just about to buy one. I will have to
check into this further.

Well ok, then. That's one box checked off.

Interesting. I didn't know that but then again, have never used GPT.

Yeah, I getcha on that. I've discovered Win7 works just fine in VirtualBox for Linux, and a super important program I need for my business does indeed install and work ok inside this VM. So for sure I'll just Win10 on a separate volume (ssd) for esoteric programs my kids will need for school. Other issue I have to figure out is MS Office vs LibreOffice. I've already run into compatibility programs when trying to load PowerPoint projects made by the kids at school into LibreOffice. Pretty much a fail but I'll figure it out.

Good!

Oh Terabyte, back to your classic "as few words as possible" posts. When you say "some systems" are you referring to laptops and their proprietary hardware/BIOS arrangements? Or are you referring to some of the motherboard manufacturers out there? Could you PLEASE elaborate a bit more??

+1

There is nothing in my new PC's manual about making any specific
settings differently to boot from an NVMe SSD drive. I'd also be
interested to hear more on this topic

Just had this back from Gigabyte support, "To boot from M.2 PCI-E you
need to be in UEFI mode as legacy does not support PCI-E Boot".

Does that mean that the disk has to be GPT formatted too? Being in
"UEFI mode" is not that clear. Can anybody please elaborate.

I was afraid of this. AFAICT when in UEFI mode your boot partition MUST be GPT formatted. I think I'm going to mosey on over to the Gamer Nexus Discord channel and talk to some of the system builders there. When I get something concrete I'll post it here. Geez what a freakin bummer!

I'm just glad I found out before buying. I really do not want nor need
GPT and would happily get a regular SATA SSD. I have seen how much of
a boost that even those babies can give.

For my personal computing needs, GPT/UEFI on a booting drive is a
totally unnecessary complication.

Ok, so after talking with some hardcore system builders it appears that you must have UEFI enabled in order to boot from an NVMe SSD. They sort of flamed me a bit because they said it's better and boots faster than legacy, and couldn't understand why I didn't want to use it. Then I asked them if I used legacy mode to boot off a normal SATA SSD, would my system even recognize an NVMe drive installed in the M.2 slot? Most of them said no but a couple others said no problem. So now I just don't know what the hell to do. :(
