Installation/start Windows ok, but SSD missing in Bios when VMD Enable.

Hello everyone,

This thread is not a problem.
I wanted to share my experience of clean installing Windows 11, with VMD enabled and disabled. And probably understand why my SSD is not automatically detected by the BIOS when VMD is Enabled.

VDM Enabled:
Windows installation and startup works fine with the RST drivers installed.
But :
1) My NVME SSD is no longer detected and displayed in BIOS. I never figured out how to display it!
2) WinRE has significant problems: Startup setting and other options are missing, restoring to a later date does not work and indicates that I have to choose a version of windows to restore!
These 2 points are linked.

VMD Disabled:
- Windows installation and startup works correctly, without the need to install RST drivers.
- My NVME SSD is correctly displayed in the bios.
- WinRE works perfectly!

I don't have a problem with VMD being disabled. And I even feel like my SSD is faster.

But I want to understand.
How to make SSD detected in BIOS when VMD Enabled.
I searched through BIOS options for hours and never found a solution.
Before this new installation of Windows, my laptop was delivered with VMD activated and the SSD clearly displayed. So it's possible.

Have a nice day.

Bios when windows is installed with VMD Enabled.

Information below is from Asus - [Motherboard] Troubleshooting - Cannot find the hard disk drive or SSD(M.2) after motherboard powers on | Official Support | ASUS Global
Follow these steps and below to see if it can be detected and maybe a BIOS update if a newer version is available

After the computer powers on, please immediately press 'delete' key on the keyboard to enter EZ Mode.

(If the computer enters BIOS Advance Mode after you press 'delete', you can press 'F7' again to enter EZ Mode)



Note：For the old models (ex: TUF B450-PLUS GAMING) ,which use PCIE Mode M.2 SSD(including: NVME M.2), information of hard disk or SSD doesn't show in Storage Information in BIOS EZ Mode due to the framework of the BIOS. This phenomenon is normal, please be noted.

3. Please enable [CSM] in BIOS

a. After the computer powers on, please press 'delete' to enter EZ Mode, and then press 'F7' to enter Advanced Mode as below:



b. Click [Boot] - [Launch CSM]. Please set [Launch CSM] as [Enabled] as below:



c. Press 'F10' to save the BIOS setting, and click [OK] to reboot. Confirm whether the computer can recognize the hard disk or SSD



4. If you have set CPU overclocking or Memory overclocking, the computer may not detect the hard disk or SSD due to overclocking instability. Please set BIOS to the default setting by the below steps:

a. After the computer powers on, please immediately press 'delete' key on the keyboard to enter EZ Mode (you can refer to the picture in step 2)

b. Press 'F5' to set the BIOS to default setting, then press 'F10' to save BIOS setting and click [OK] to reboot. Confirm whether the computer can detect the hard disk or SSD.

Thanks for your response, but I've already read this Asus FAQ.
It doesn't help me.

I just want to understand how BIOS detects and displays SSD when VMD is enabled in this BIOS version.
Windows boots, but the SSD isn't display by the BIOS.
