Is NVME not Detected in BIOS? 3 Ways to Fix It Now

If your NVMe SSD isn’t showing up in the BIOS, you won’t be able to access or use it for storage.

But you don’t have to worry. In this article, we’ll outline the causes of this problem – such as improper connection, CSM issues in BIOS, and outdated software- and explain step-by-step how to address them.

What can I do if NVMe is not showing up in BIOS?

1. Configure M.2 SSD

NOTE

The steps listed below might be different for your computer, but they should provide a basic understanding of the concept. If you are still unsure, head to the OEM’s website for the exact steps.

1. To access BIOS, turn on your computer and press the F or DEL keys, depending on your motherboard manufacturer. This key can be different based on your motherboard.
2. Next, head over to Storage Configuration.
3. Under SATA Configuration, click on Configure SATA as.
4. Then, choose IDE by pressing Enter.
5. Finally, press F10 to save your new BIOS settings and exit.

If you configure your SATA device to something other than IDE in BIOS, your NVME drive may not show up.

2. Disable Secure Boot

1. First, reboot your computer and press the dedicated key for your motherboard to get into BIOS.
2. Next, go to the Security tab and click on Secure Boot.
3. Select Disabled from the menu.
4. Then, head over to the Save & exit tab.
5. Press Save Changes and select Yes afterward. Make sure not to choose Save Changes & Exit.
6. Go to the Security tab again.
7. Choose Delete all secure boot variables and select Yes.
8. Finally, select OK to reboot your computer.

3. Set PCIe setting to M.2

1. Reboot your PC and press the designated key for your motherboard to enter BIOS.
2. Select Advanced Settings. For some motherboards, you can also press F7 to access the menu.
3. Then, under Onboard Devices Configuration, search for PCI Express slot Bandwidth.
4. After that, set its value to M.2 mode if it is not already that.
5. Press F10 to save the changes and exit.

Setting PCIe to M.2 is one of the simplest and most effective ways to resolve the NVMe not showing in the BIOS problem.

Are M.2 SSDs faster than SATA SSDs?

SATA SSDs use the AHCI (Advanced Host Controller Interface) protocol and have a faster data transfer speed, nearly 600MB/S. However, this is not the case with M.2 SSDs.

Those are keyed to avoid the insertion of a card connector into a non-compatible socket. They typically use three keys which are B, M, and B+M.

If these storages use a B key, are connected to a Socket 2, and support NVMe protocol, the M.2 drive is at least three times faster than a SATA SSD.

However, if it uses an M key, is connected to a Socket 3, and supports the NVMe protocol, the M.2 drive is at least seven times faster than a SATA SSD.

One thing worth mentioning is that if you want your modern devices to be recognized by your computer, you need to keep your BIOS updated.

If you fixed NVMe hard drive not showing up in BIOS, but now your system does not recognize your M.2 SSD, make sure to update your M.2 driver.
