I had two 970 Samsung Evos in one of my computers. Occasionally one wasn't seen. This was fixed by disabling Fast Boot in the BIOS.

When I had my issue, Fast Start was already disabled. You told me to disable Fast Boot and it worked.

Edit... I checked my email from 2018. The M.2 drive wasn't seen in BIU after a restart, but it was still seen in Windows . BIU saw the M.2 drive after a Save and Exit in the BIOS. But only once.

Running IFW with CPU priority (/priority:n) option in "background mode" can really slow things down as well.

See page 156 if the IFW User's Manual.

I was talking about the potential issues of why it wouldn't boot.

But yes, for hardware not seen, you can disable that to ensure full post by BIOS.
