Why isn’t My M.2 Drive Not Showing Up
Finding why your M.2 drive is not showing up is halfway to solving the issue. There are several reasons behind a drive’s disappearance, and you need to find the exact one that is causing you trouble.
In order to aid you to resolve the matter, I have arranged the best possible reasons behind vanishing an M.2 drive in the boot menu.

Here are the probable causes:
- Outdated disk management program: Disk management is a system utility that helps you to carry out advanced storage tasks. This is mainly for installing a new drive and extending a volume that already exists. If the mainframe of the utility is outdated, it might be slightly problematic to show up a new drive.
- Enabled Secure Boot: Secure boot detects interfering with boot loaders, key operating system files, and Illegal ROMs by confirming their digital signature. When you install a new drive, it automatically blocks the detection in order to avoid system attacks. It may be one of the reasons why your M.2 drive is not showing up.
- Enabled Compatibility support module: The compatibility support module (CSM) follows a BIOS environment that is harmonious with your operating system. Enabled CSM doesn’t allow most modern drives to authorize UEFI on your system; hence your M.2 SSD remains undetected.
- Shared bandwidth with other ports: In most motherboards, M.2 ports are shared with other PCIe slots and other SATA slots. That means, if you install an M.2 SSD, your SATA ports get disabled, or if you install a SATA drive, your SSD gets disabled. So, before buying an SSD, read your motherboard manual to avoid such a scenario.
- Conflicting Driver letters: Imagine your existing driver is being indicated by C:/ and the new SSD you installed is also being dictated by the same driver letter. It may cause the SSD gets vanish from your system. Check if the drivers are being dictated with the same letter.
