CMS Support disable

[M4rcus90]

Hello. I have a problem with my BIOS. After disabling CSM Support, to enable Secure Boot am I unable to go to BIOS after reboot. Computer just goes to Windows log on screen after reboot, without possibility to go to BIOS. Do you know what could be the problem? Thank you.

I have a GIGABYTE z390 Gaming SLI motherboard

There's a way to force access your bios via windows, as long as u got a UEFI installation.

 

Click on your windows logo -> select shutdown options -> hold shift while clicking on restart -> wait for the new window and click troubleshoot -> click on UEFI Firmware Settings.

PC should reboot into BIOS now.

I already did that, but computer still doesn't reboot into BIOS, it just goes back to Windows log on screen. I do have a UEFI installation, as you can se from the picture.

Saw the following in a different thread with same MB Manufacturer and problems:

 

Push the power button to start the PC and immediately after hold the reset button for more than 10 seconds. Mainboard should give a beep and u should be able to access bios via "del" key.
