Windows 10: M.2NVMe SSDs and hard Drives not recognized as bootable devices!

This is a new build on ASUS z690-Creator ProArt WiFi motherboard with BIOS Ver. 0702. CPU is Intel i9-12900kf and the drive I want to use for Windows 11 Pro OS is Samsung 1TB 980 Pro M.2 NVME. Also installed on Motherboard is a 2TB M.2NVME Samsung 980 Pro, and two 2TB Samsung 970 EVO Plus M.2NVMe SSDs. In the ASUS BIOS under "Boot Menu" is says: "The system cannot find any bootable devices". Under "Boot Priority" is says: "Choose one and drag the items." Then listed under "Storage Information" my four M.2NVMe drives and one other hard drives are listed. When I left click on any of these drives

Since updates can only be delayed for so long, an actual fix would be appreciated.

 

M.2 SSD no longer being recognized

Is the M.2 disk recognized on BIOS?
If it isn't, it's probably a hardware problem and you should as for a new in warranty.

If it's recognized on BIOS it's probably a corrupted software.
Boot from a Win 10 installation disk, launch a cmd window (Shift+F10) and type:
diskpart
list volume (take note of the letter assigned to your windows in the M.2 drive)
exit
sfc /scannow /offwindir=X:\windows /offbootdir=X:\ (replace X with the drive letter found with list volume)

My recommendation is to create a utilities disk Windows 10 Recovery Tools - Bootable Rescue Disk
