Windows 10: How do I enable my SSD as a boot option in BIOS when it's detected but not selectable?

How do I enable my SSD as a boot option in BIOS when it's detected but not selectable?

My m.2 ssd is recognized in bios, but not as a boot device

Thank you very much for reaching out! As an Independent Advisor and fellow Microsoft user, I'm more than happy to assist you.

Here are some steps you can take to troubleshoot and potentially resolve this issue:

1. Check BIOS Settings

Ensure that your BIOS settings are correctly configured to recognize the M.2 SSD as a boot device:

• Enable CSM (Compatibility Support Module): Sometimes, enabling CSM can help the BIOS recognize the SSD as a boot device. You can find this option under the Boot tab in the BIOS settings.
  
• Set Boot Priority: Make sure the M.2 SSD is set as the first boot device in the boot priority list.
  

2. Update BIOS

Updating your motherboard's BIOS to the latest version can resolve compatibility issues with new hardware:

• Visit the ASUS official website to download the latest BIOS update for your ROG Strix B650 Wi-Fi motherboard.
  

3. Reinstall the SSD

Ensure that the M.2 SSD is properly installed:

• Remove the SSD and reinsert it firmly into the M.2 slot. Make sure it is securely fastened with the screw.
  

4. Initialize the SSD

If the SSD is new, it might need to be initialized:

• Boot into Windows using another drive, open Disk Management, and initialize the SSD as either MBR or GPT.
  

5. Check for Drive Mode Compatibility

Ensure that the M.2 slot you are using supports the type of SSD you have (SATA vs. NVMe):

• Some M.2 slots only support either SATA or NVMe, not both. Refer to your motherboard manual to confirm compatibility.
  

6. Repair Boot Configuration

If the SSD has Windows installed but is not recognized as a boot device, you might need to repair the boot configuration:

• Boot from a Windows installation USB, go to the command prompt, and use the following commands:
  
  
  This can help rebuild the boot configuration data.
  

7. Check for Hardware Issues

If none of the above steps work, there might be a hardware issue with the SSD or the motherboard:

• Test the SSD in another system to see if it is recognized as a boot device.
  
• If the SSD works in another system, the issue might be with the motherboard. Consider contacting ASUS support for further assistance.

Automatic repair while booting from hdd and installing windows on ssd.

1. Migrated windows from hdd to ssd
   
2. Formatted hdd
   
3. Prioritised boot from ssd in bios
   
4. Turned on the pc
   
5. Automatic repair
   

To deal with this I select boot from a device > then EFI USB device > it says no bootable USB detected, select from these drives > there are few options including the newly installed ssd > I select ssd > then it shows disk checking, press any key to stop > I stop it > windows then boots from ssd.

It very difficult to repeat all this everytime I turn on my pc. Please suggest a fix.
