M.2 SSD with an Asus Z270E Motherboard

[Elizabeth_47]

I recently got a new Samsung M.2 SSD and I'm wanting to make it my new boot drive on my desktop. I'm using an ASUS Z270E Gaming Motherboard with the latest BIOS update. I have a regular SATA SSD installed that's currently my boot drive, and two HDD's as extra storage. So I physically installed the m.2 drive (and moved the SSD which was plugged into SATA port 1 to a different spot, because the m.2_1 slot disables SATA port 1). Then I used the ASUS clone drive software to clone my SSD to the new M.2 drive, which worked fine, but when I reset and try to boot off of the new drive nothing happens. In the ASUS BIOS when I'm choosing what to boot off of, my SSD shows up twice, once just with it's name and where it's plugged in again as "Windows Boot Drive: (SSD name).." and this is the one I use to boot. The new M.2 drive shows up but just the regular one and not the "Windows Boot Drive:..." version of it. When I boot off of my regular SSD it also doesn't show up when I go to "This PC" in file explorer. So I know I installed it correctly because it showed up in the clone drive software, but I can't figure out how to correctly boot from it. As a note, I've changed the advanced settings in BIOS so the m.2 slot is in pcie mode(was in auto), didn't fix anything. Can anyone help?

Samsung M.2 SSD

You've neglected to list which Samsung M.2 SSD you are referring to. If it is SATA or NVMe PCIe makes a difference. You may need to do a UEFI install of Windows 10 for the drive to operate.
