Windows 10: M.2 SSD stopped being detected

Hi guys, a few years back I bought a 250GB M.2 ssd as an extra storage to my laptop. I already have a Samsung 500GB for OS. After 2+ years, my 250GB suddenly stopped appearing. I checked the device manager, disc manager and the BIOS. I used "diskpart and "list disk" command on cmd just to be sure and it's not detected. I tried removing and reattaching it but to no avail. I switched the 500GB OS into the 250GB slot and vice versa to see if the slot on my motherboard is faulty but it detected the 500GB OS just fine. Then, I replaced the ssd entirely and it only detected the new ssd for 3 days be

SATA SSD and M.2 SSD

i was with a ssd sata and now i have ssd m.2, i formatted and put windows 11 in m.2, but i did not remove the ssd sata, i can only boot windows with the ssd sata connected, if i remove it windows does not boot to m.2



obs: windows was installed on m.2 but the ssd sata was still connected, but windows was 100% installed on m.2, is there any way I can set m.2 as primary? (when i removed the ssd sata it did not recognize windows)

Sorry for my bad English

M.2 SSD not being able to boot from it, windows doesn't recognise.

Ok, this is what happened after all the comments and suggestions, @dude: Thanx for the video, my mb had non e of those settings, it had the raid/option memory gene or achi. Can only choose one or the other. @Saltgrass, my settings did point out auto and enabled the pcie x4, gen 3. I did an bios flash as suggested, because my bios was not the latest version, after a reformat the m.2 was picked up, still cant install OS onto it as it states legacy not found, removed my dvd rom from the sata port to another, and the drive was found and installed. Only issue now is that it's still not my OS drive but it at least now works and is installed, but on the Intel rst drive the obtain memory gene option to enable is greyed out, and shows as disabled. However the program lists the M.2 and it is working 100%,. I installed overwhatch onto it, it performs perfectly. But will update the intel driver tonight and see if that makes any difference. Seems the bios flash enabled the settings listed by @dude that was not present pre-flash.

So the m.2 drive works. I can game off it and install omnto it. Can not install windows on it, gene memmory is enabled, pcie x4 is on and on auto detect, Motherbaord lists all the drives connected, motherboard ahs been updated to latest bios. After flash new settings became available, m.2 is now on memmory gene enabled not achi, windows os is enabled and fast boost is enabled, intel rst is installed and lists all the ssds and the m.2, however the m.2 on memmory gene is dissabled and the option to enable is greyed out. Will update the driver as Essenbe suggested of the m.2 and see if anything changes. Thank you all for the help, I can now atleast use my m.2

 

Standard NVM Express Controller driver error m.2 ssd not detected

So at the moment I have two m.2 SSD's installed in my pc. The 250gb one is what I am currently using. However, I want to use a Corsair mp510 2tb gen 3 m.2 as well but it cannot be detected in BIOS or Windows. Then I looked in device manager and the Standard NVM Express Controller driver states this error:
This device cannot start. (Code 10)
An I/O adapter hardware error has occurred.
How can I try and fix this? I spent days trying to get the SSD to work after building the pc, until I decided to get another m.2 to install windows onto. The motherboard is an x570s tomahawk max WIFI. Also I am sure it's an issue with the SSD as it didn't work in the other m.2 slot either.
