No boot via Samsung M.2 EVO NVME plus SSD. Boot via sata SSD 1 is fine. Max XI wifi

I used Samsung data migration to clone my SATA SSD to my new Evo plus M.2 SSD. On the old rig, no problems at all. Cloned SSD worked perfect when removing c/ SSD .*
Moved afterwards this new cloned *SSD into M.2_1 slot of my Max XI but I simply fail to find the right BIOS settings as the M.2 doesn’t get recognized. Through luck , I spotted at a certain moment the 4 SSD drives being visible in boot menu, but changing some bios setting resulted in not finding the M.2 SSD . Help*:D

Turn off CSM and try again. See if that helps.

Did you boot the drive into windows first, and create an image? I can't recall the actual setting, but I ran into this with an 860 Evo on my laptop, and ended up having to reinstall windows because it wouldn't see the boot sector. When I went from another 860 to 970 evo, I did the same setting under disk utilities in Windows.

I made it work (using the cloned bootable image )by disabling NVME in bios and forcing sequence by removing old c drive, but the boot time is tremendously long. I was able to install the NVME Samsung driver, it’s visible in the bios but it’s just half slow vs my previous build.
Looking further into it

Didn’t made any difference, but disabling everything which smells raid or SATA did the trick to boot from M.2 *
