Windows 10: Set secure boot on Asus b450m-a motherboard

I'm trying to set secure boot on Asus b450m-a motherboard to be able to use Win 11. I have tried various combinations of CSM settings and Secure Boot settings but haven't been able to achieve it. The PC Health App tells me that TPM 2 is enabled but Secure Boot isn't. Can anybody help please.?

Yeah, now I understand your confusion *Smile

I'm looking at the logitech user guide and that guide is completely useless.

What is clear to me is that you want to connect the green cable to the green connector on the speakers and the lime (green) connector on the motherboard.

The other two cables are a mystery but we can easily figure that out!

My suggestion:

Plug the black cable into your speakers, and the other end of that black cable into the light blue connector on your motherboard. Light blue is the connector for the rear speakers. So now we simply need to test to see if sound is coming out of your rear speakers.

Right-click the speaker icon on your task bar and select Sounds:





Select the correct audio device and then click on Configure:





Click on one of the rear speakers to test sound. Note: In the illustration below, I have no rear speakers so that illustration only has the front speakers:





If the sound comes out of the rear speakers correctly then the black cable is connected correctly. Now, simply connect the orange cable to the remaining connector on the motherboard and to the orange connector on the speakers.

If you are not getting sound from the rear speakers, swap the black cable to the pink connector on the motherboard and test again. Again, plug the orange cable into the orange connector on the speakers and the remaining connector on the motherboard.

Let me know if this all works!

 

Error 800703EE & Asus secure boot

Apologies for my tardiness. Install was created via Media Creation Tool.

I switched from usb 3.0 to a usb 2.0 port and the install worked. My partition style is Legacy bios compatible, not GPT, but I'm alright with that. The steps for disabling secure boot can be found at How to Disable or Enable Secure Boot for ASUS Motherboard but my searches initially didn't turn up anything.

Drive had been wiped. Also, it did format using NTFW of course.


Thank you everyone.
