System needs Windows 11 and Secure Boot activated in BIOS.
I'm attempting to activate Secure Boot for Windows 11, but it isn't working. I had Windows 10 installed in legacy UEFI mode initially. Now I'm trying to switch to UEFI without reinstalling it, but the system warns me to disable the CSM and reboot afterward. I need guidance on how to handle the CSM or properly enable Secure Boot. Let me know.
Your issue seems to be with the CSM (Compatibility Support Module). You need to switch the setting to UEFI only. It’s likely fine to boot into Windows since your drives are configured for GPT. To adjust the setting: BIOS > ensure you’re in "Advanced Mode", not "EZ Mode" (press F7 if using EZ Mode). BIOS > go to the Boot page Boot Mode Select > UEFI
I adjusted the settings to "Boot Mode Select > UEFI" but encountered the same issue with enabling secure boot.
I understand you're asking about drive requirements and why some drives might not be treated as GPT. It's important to clarify that not all drives need to be GPT—typically only the boot drive is required. If your non-boot drive isn't set as GPT, it could be due to configuration settings or system defaults.
You don’t have to make your non-boot drive a GPT partition to use UEFI. Both are marked as UEFI in the BIOS, but the command prompt indicates your non-boot drive isn’t a GPT partition.
