The motherboard isn't recognizing your M.2 SSD, which means you won't be able to start your computer.
I just received a new motherboard and needed one with Wi-Fi. I replaced everything from my old board. This model has two M.2 slots, so I placed the 860 Evo in one (with all its features) and the 970 Plus in the other. When I tried to boot and went to BIOS, neither device showed up. Help me, I can't get my PC to start.
Verify your boot sequence and confirm the 860 EVO comes before the 970 plus. Also, consider that Windows licensing depends on the motherboard's SN, unless updated via a Microsoft account.
Please share an image showing the SSD placement on the motherboard. The BIOS settings should reflect "PCIe SlotX Lanes Configuration" under Advanced (F7) > Settings > Advanced as "Other M.2". List the populated PCIe lanes and specify which M.2 slots you have installed—such as 2_2 being unavailable for any slot in PCI_E2, PCI_E3, PCI_E4, or PCI_E5. Note that for this board and configuration, the 860 Evo M.2 must go into M2_1 while disabling SATA ports, and the 970 Evo Plus M.2 needs to be in M2_2 with PCI_E2 disabled.

I own an MSI X570 Carbon Pro with both M.2 slots filled. The Samsung 970 EVO is installed in the top slot, WD Black in the bottom slot. What stood out between your BIOS and mine is the use of CSM versus UFEI. I recommend navigating to advanced settings—ensure under 'advanced' that your SATA controller is set to AHCI. I don’t want to rely on the main page’s ‘easy mode’ since it’s not reliable. Then, in the OS operation menu, switch from CSM to UFEI. I didn’t need any adjustments or changes to the PCI settings to get it working; everything stayed on AUTO.
