    Hi @ilay shemi ,

    Thanks for reaching out!

    After researching, Secure Boot depends on a few conditions:

    • UEFI Boot Mode must be enabled (Legacy/CSM mode will block Secure Boot).
    • Windows must be installed on a GPT-partitioned disk. If your OS uses MBR, enabling Secure Boot will fail.
    • Secure Boot keys need to be loaded in BIOS.
    • Outdated BIOS firmware can also cause issues.

    If any of these are misconfigured, the BIOS may prevent saving changes.

    Here's a few steps you can check out:

    1. Check BIOS Settings

    • Disable CSM (Compatibility Support Module).
    • Switch Boot Mode to UEFI.
    • Look for an option like Install Default Secure Boot Keys and apply it.

    2. Verify Windows Installation

    • In Windows, run msinfo32 → Check BIOS Mode (should be UEFI) and Secure Boot State.
    • If BIOS Mode shows Legacy, your disk is likely MBR.

    3. Convert MBR to GPT (No USB Required) (Optional)

    • Use Microsoft’s mbr2gpt.exe tool from Windows Recovery or Safe Mode.

    4. Update BIOS

    • Download the latest BIOS for your motherboard from Gigabyte’s support page.

    For step 2 and 3, I recommend you search them with keyword like below for better details:

    • Secure Boot won’t work until converted to GPT.
    • Convert MBR to GPT without data loss.

    You can also try searching: "How to enable Secure Boot for Battlefield 6" or things similar to that. I find there are a lot of articles or videos that cover this with tutorial so please give it a try.

    Note: Since you are searching in third-party websites. Do not download any strange links or entering any personal information.

    Hope this helps! If you have any questions, please leave a comment blow!
