Question Can't disable CSM support and enable secure boot on Gigabyte B450 Gaming X ?

[jds394]

Hi there,

I'm trying to enable secure boot on my computer to be able to pass the spec check for windows 11, but I cannot disable the CSM support first in order to then enable secure boot.

Every time I try to commit the configuration change of "CSM support = Disabled" and restart the computer, the setting shows up as enabled when I re-enter the BIOS ?

How do I determine what is preventing it.


My system:
GigaByte B450 Gaming X
AMD Ryzen 5 2600
16GB Cosair DDR4 (8GB x2)
NVIDIA GeForce GTX 570
Windows 10 Pro 64bit
AMI BIOS version F51

Any suggestions greatly appreciated.
Josh

You must choose the "Save & Exit" option in the BIOS, otherwise any changes you've made will not "stick".

Thanks Philip I'm definitely following the same & Exit route but the change is not being committed and there are no errors or warnings indicating that it can't be. The computer then restarts and I go to check that the change has been made and the setting shows back up as enabled regardless

Here is a link to a Video of what I am trying to do?

I tried to look at your video, but only got one single picture.

Has your boot drive been converted from MBR to GPT?

I have the same issue. I have converted the drive from MBR to GPT following this video but then, when I disable the CSM support and restart, it automatically goes back to on. Any idea of what I am missing?
