I was attempting to switch to Windows 11, but everything seems okay except for SecureBoot. When I enable SecureBoot, the main drive (Samsung 980 500GB) vanishes from the boot list and reappears when SecureBoot is turned off. Anyone have a solution or similar issues? I need the SSD as a boot choice since my OS is installed there.

Format the boot drive using GPT instead of MBR, and turn off CSM mode so SecureBoot can work properly.

You can check your SSD type by using system tools like Disk Management or the Command Prompt. If it's MBR, you typically need to reinstall Windows to change the format. GPT is usually supported during installation and recovery processes.

Your drive is fully MBR-based, but converting it to GPT depends on your operating system. Check if your OS supports GPT conversion and follow the appropriate steps for your specific system.
