I'm unfortunately back with another issue.  Ever since I resolved my previous issue a few months ago, my system has been working great.  That is, until today.  On Friday, I shut down my computer for the weekend.  I turn it on today, and all of a sudden it was asking me to choose a boot device.

I have Windows installed on an M.2 Samsung 850, but it is now for some reason not showing up as an option to boot from in the UEFI.  My other three 3.5 inch drives do show up in the list.  You would think that would indicate failure of the M.2 drive, but it does show up in the list of drives under Storage Configuration.

I tried loading UEFI defaults, but the M.2 still does not show as a bootable drive.

I tried updating the UEFI to V7.10, but that didn't fix the issue.  I have reverted back to V3.10.

Any suggestions?

Mobo: Z170 Extreme 7+, UEFI v3.10
CPU: i7 6700K, no overclocking
RAM: 32 GB (4 x 8 GB) Corsair LPX DDR4-3000

PSU: Corsair HX850i
CPU Cooler: Corsair H100i GTX
