I'm Unable to disable the CSM
I have updats the BIOS to 1.61 and done the following: -
Step1. Disable CSM at the path Boot\CSM (Compatibility Support Module) in the BIOS.
Then press F10 to save the settings and restart.
Step2. Set Secure Boot Mode to ?œCustom?? then click ?œInstall default Secure Boot keys??at Security\Secure Boot page under BIOS.
Then press F10 to save the settings and restart.
Step3. Enable Secure Boot at the path Security\Secure Boot in the BIOS and press F10 to save the settings and restart.
This is the last instruction that I got but they don't want to help "Not their problem"
"If the problem still persists, we recommend contacting local distributor for further assistance.

Hi Kymxxxxxx,
Thank you for your posting.
CSM will be disabled after doing step 1.
If you plan to turn off CSM to upgrade to Windows 11.
We recommend backing up all your DATA and installing Windows 11 directly.
Windows 10 which installed under CSM enabled is not able to upgrade to Windows 11.
You need to clean your disk and install Windows 11 with CSM disabled.
All the best

Thanks for the help but step 1 does not stick. When I go back and check it it's always enabled and hence no matter what I do Windows 11 will not install.
