Enabling or disabling Secure Boot ensures that your system boots using only software that is trusted by the PC manufacturer. Here's a step-by-step guide for doing this on an Asus ROG Strix Motherboard, though the steps are generally similar across different systems.
Enter BIOS: Begin by restarting your computer and entering the BIOS setup. The key to press varies by manufacturer—common keys include F2, F10, F12, or DEL. If you're unsure, refer to your motherboard's manual or our article on 'How To Enter BIOS or UEFI by Manufacturer'.
Switch to Advanced Mode: Once in the BIOS setup, switch from Easy Mode to Advanced Mode by pressing F7 or clicking on the 'Advanced Mode' option.
Disable Compatibility Support Module (CSM): Before you can enable or disable Secure Boot, ensure the Compatibility Support Module (CSM) is disabled or Boot Mode is set to UEFI Mode. This might be found under the Boot tab. Refer to our article on 'How To Disable or Enable CSM in BIOS' if needed.
Locate the Secure Boot Option: Find the Secure Boot option, typically located in the Security, Boot, System Configuration, or Authentication tab.
Enable or Disable Secure Boot:
- To enable Secure Boot, set it to 'Windows UEFI mode'.
- To disable Secure Boot, set it to 'Other OS'.
Manage Secure Boot Keys:
- If disabling Secure Boot, you may need to clear the Secure Boot keys. Navigate to Key Management and select 'Clear Secure Boot Keys'.
- If enabling Secure Boot, install the default Secure Boot keys by going to Key Management and selecting 'Install Default Secure Boot Keys'.
Save Changes and Exit: Finally, save your changes and exit the BIOS. You can do this by going to the Exit tab and selecting 'Save Changes and Reset' or pressing F10.
By following these steps, you can effectively manage the Secure Boot settings on your BIOS.
