Part 3. How to fix the M.2 drive not showing up in BIOS

For PCs, BIOS (Basic Input/Output System) is firmware that provides runtime services for OS and programs along with hardware installation during the boot process. The BIOS also initializes and tests the system hardware components and loads a boot loader from a mass storage device.

In theory, M.2 is visible to you in your BIOS after a fresh install of an M.2 SSD on the motherboard. But in practice, your newly added M.2 drive might not show up in BIOS.

Fix 1. Configure your M.2 SSD drive

If your M.2 drive not showing up in Windows 10/11, you’re supposed to check whether your M.2 drive is enabled in BIOS or not. Please refer to the following steps.

Step 1. Restart your computer and press “F2” or “Delete” to get into BIOS.

Step 2. After entering the BIOS, expand SATA Configuration and select Configure SATA as “IDE” mode.


Step 3. Press “F8” to save these changes. After exiting the BIOS, reboot your PC to see if your M.2 drive is visible to you or not in the BIOS.

Fix 2. Reinstall M.2 SSD drive

Sometimes, incorrect installation could lead to your M.2 drive not showing up in BIOS. Please disconnect your desktop or laptop computers from all connections first, then you are ready to reinstall your M.2 SSD drive.

Fix 3. Disable Secure Boot in BIOS

Deactivating Secure Boot in BIOS is another practical solution to fix your M.2 drive not showing up. Let’s show how it works.   

Some motherboards only have Secure Boot but not Secure Boot Control. At this point, you just need to set Secure Boot to Disabled.

Step 1. Restart your computer and press “F2” or “Delete” to enter the BIOS.

Step 2. Go to the Security interface and click the “Secure Boot” button.

Step 3. Set “Secure Boot Control” to Disabled.


Step 4. Remember to save these changes before exiting the BIOS. Then reboot your PC to check whether your M.2 drive shows up or not.

Fix 4. Update BIOS

When you connect a modern device to your motherboard, an outdated BIOS might fail to recognize the new technology. That’s one reason why your M.2 SSD was not detected in Windows 10/11.  

Updating the BIOS is a good method to accept and adapt to these changes. Please don’t interrupt the update and avoid any power failure to damage the motherboard during the update.

Step 1. Download the BIOS update file from the official website of your Windows PC’s motherboard manufacturer.

Step 2. Load all the updated files into a USB flash drive and reboot your computer.

Step 3. Connect your USB drive to your PC and enter the BIOS interface.

Step 4. In the BIOS interface, select the “Update BIOS From Drive” option. Then select the BIOS update file downloaded from the USB stick.


Please confirm this operation and wait for the update process to complete.

Fix 5. Check M.2 Settings in BIOS

For SSDs, modern motherboards and laptops usually have two M.2 SSD slots. In some cases, the M.2 drive not showing up might be caused by incorrect BIOS settings. Thus, it’s critical for you to check M.2 settings in BIOS to ensure everything runs smoothly.

Step 1. Restart your computer and get into the BIOS by pressing the “F2” or “Delete” key.

Step 2. Click the “Advanced” settings tab > Onboard Devices Configuration.

Step 3. Tap on the menu next to PCI Express X4_3 Slot (Black) Bandwidth and click the “M.2 mode” button.


After exiting, you can restart your PC and get into the BIOS to check your M.2 drive.

Fix 6. Change boot priority to M.2

To some degree, a faulty boot order may prevent Windows from detecting your properly connected M.2 drive and loading the software. If the above fixes cannot make your M.2 show up in your BIOS, try to change the boot priority to M.2.

Step 1. Restart your computer and enter the BIOS by pressing the “F2” or “Delete” key.

Step 2. In the BIOS interface, go to the Boot tab. Then locate the boot priority order.

Step 3. Move your M.2 drive to the first and change the boot priority to your M.2 drive.


Step 4. Press F7 to save these changes.

Part 4. How to fix M.2 drive not showing up in Disk Management?

Step 6. In the initialize window, select “MBR” or “GPT” based on the capacity of your M.2 drive. Then click the “OK” button.


Step 7. After initialization, right-click on the unallocated space of your M.2 drive and select the “New Simple Volume” option.


Step 8. After setting the partition size and new drive letter of your M.2, click Format this volume with the following settings > Next. Please ensure the file system is NTFS.


Step 9. Then click “Finish” to close the last window and go back to the main interface of the Disk Management utility.
