Any help welcome here, I can only boot by hitting F8 and manually choose my m2 drive.
There seems to be an option missing here for m2 mode?

And this is what I have for m.2 link mode:

The memory on the other hand, DCOP profile 4 (apparently 2666MHz) is reported as 2.9GHz bt CPU-Z:

And works spot on without issues.
Though Userbenchmark detects it as correct 2666MHz:

Compared to MSI, anything above 2133MHz would result is crash hangs or boot failure. Lately I had random reboots with MSI X370 so I swapped to Asus now.
OK, I installed a bootloader to the Intel SSD, got the drives in good condition now:

FYI: on the first Windows install to the m2 drive, it created an MBR partition, those cannot boot UEFI. I did now remove all drives, reinstall Windows 10 64bit from USB and it created a GPT table, in fact it warned me this time I cannot install to MBR.
It created a small partition with the nvme driver and boot information, one small recover partition (400MB) and the main partition for the OS.
As boot drive I now use "Windows m2 Boot Loader"
