Windows 10: m.2 and windows boot manager not showing up in bios

Hey, I have the b550 aorus elite and Im attempting to install windows onto an m.2 ssd. when installing windows, it recognises the m.2 however after installing, it is not recognised in boot sequence. also, In boot sequence, the Windows boot manager is not showing up at all. I have a samsung evo 970 plus 1tb. and I've installed windows several times on the drive but It still doesn't show up.

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.

 

Windows not recognizing new m.2 NVME SSD but shows in BIOS

I purchased a crucial nvme m.2 ssd for my MSI GT73 Titan - It shows in the PCIE section of the BIOS but does not show in disk management - Also does not show up in Crucial's Storage Executive Application.

My BIOS is the latest version.

Any ideas?

 

No Boot, Drives Not detected, Can't Load Win10 Pleses Help!

Until the BIOS sees your M.2, there's nothing you can do. It does not matter if the M.2 is unformatted/unallocated, the BIOS should see it.

1. Suggest that you take the M.2 out, clean all the contacts and re-seat it and hope this is the case.
2. If step one fails. Connect your 250GB SSD back in using one of the SATA port to see if the BIOS recognize it. If it doen't, then it might be something wrong with the MB, if it does then boot up the Windows Installation USB, run diskpart, shrink it at least 40GB then create a partition, Leave it unallocated then install Windows there.

Also try to re-seat all other components such as Memory, Video card etc...
