Windows 10: why wont my m.2 show up

ive looked in the the disk management, files, and even tried bios and reslotting everything. how would i fix this?

:)

 

M.2 SSD doesn't show up in BIOS, Windows Installer and Disk Management

This depends on where in the bios you are looking. I have a Gigabyte X470 board and in the drive list I only see my CDROM, but in my boot order I can select either of my two M.2 drives. Keep in mind that some M.2 will show up as they are SATA drives but most are NVMe drives. If you are still unable to select your M.2 drive as a boot option then you need to look into updating the BIOS of the board as some M.2 drives are not recognized in the early firmware for the X470 boards.

It is also worth noting that on most of the X470 boards the second M.2 slot is shared with the adjacent PCIe slot and if something is in the PCIe slot the M.2 port is inactive. As well some BIOS wont see an M.2 drive in the second slot if noting is in the first slot. Some BIOS updates have fixed this problem.

 

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

 

M.2 Disk not showing up in Windows

Windows 11

Motherboard: Gigabyte H610 S2H DDR4

Disk: Kingston KC3000 1TB

I purchased a new M.2 disk. Initially, it was working fine, I formatted it, etc. However, when I was in the process of installing a Windows 11 setup from one of my pendrives, I couldn't see the disk as an installation option, and then it disappeared. It's still visible in the BIOS and Device Manager, but not anywhere else, like Disk Manager or Windows memory settings.

I've already tried:

1. Unplugging and plugging in the disk.
   
2. Downloading drivers by selecting "Search automatically for updated driver software."
   
3. Checking if the disk is correctly connected.
   
4. Verifying if the disk is enabled in the BIOS (I don't have the option to enable/disable, but the motherboard manual states that only enabled M.2 disks show up).
