[SOLVED] M.2 not bootable in new build.

[Almog6666]

I built a new PC and took my m.2 with the OS (win 10) from my old build.
When I turn on the PC it goes to BIOS and boot sequence is empty and it say no bootable devices found..
In the last build I also had an HDD, in the new one just using the m.2

I moved from 7700k + prime b250-m
To 10600KF + Prime Z490-A

does it boot on the old system with just the m.2(unplug the hdd)?

it mean you either change the csm/uefi in bios to get it to boot
or need to do a fresh os install on the new system
