Windows 10: My windows can see M.2 SSD but my BIOS won't recognize it. Why?

I just installed M.2 SSD so I can move my old boot drive SSD for more space. I can see and access the new drive and I have cloned it but my BIOS won't see it, therefore I can't boof off the new drive.

Crucial m.2 ssd not recognized by bios post windows 10 installation

Installed windows 10 pro on my crucial m.2 ssd 500gb as us z97 board and it was fine.

Drivers updated two monitors came to life with beautiful desktop. File explorer was different, login screen was nice, start button was crisp....I played. A little bit with it and went to work. Came back and found my pc in bios.

i immediately set everything to default. And found that my crucial m.2 ssd is nowhere to be found in my bios. Hence no OS to boot from.****???

a coincidence?

I popped in another crucial m.2 ssd and its fine. Going to attempt to install again and see if it repeats....... Stay tuned guys I may have found a problem.

 

M.2 cloned from SSD dive, bios problems

OK-

cloned my Samsung ssd850 contents to my new m.2 Samsung 970. Bios will not recognize the m.2 with the ssd850 installed. Either work by themselves fine. Motherboard is Asus Gaming Aura Pro 970. My question is how can I get my Bios to recognize both and
set boot order?

Can I somehow format the 850, then back it up from the m.2?

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
