    Help with Gigabyte Mobo and Secure Boot


    I have a Gigabyte X570 Aurous Master mobo. PC health check says that my PC can't run Win 11 because I don't have secure boot. I've looked in the BIOS (under Boot menu) and I don't see secure boot anywhere.

    Would anyone know, does the Gigabyte X570 Aurous Master support secure boot?

    Disable in the bios csm support and the secure boot option should appear in the boot tab or still in the boot tab but under security option.

    If you installed Windows with csm enabled it is possible that you have an mbr/legacy installation instead of gpt/uefi. In this case after disabling csm it is possible that your Windows does not start, it will then be necessary to put the csm option back on and then convert mbr to gpt.

    windows 11 doesn't need secure boot to be enabled, it just needs to be present in the bios.

    Edit: Or it is already in the bios in the boot tab under security option but you must disable csm to configure it and for windows to detect secure boot even if it is not activated.

    you can bypass that check easily if you want to install win11.

    Here... this is from your manual. I edited the pic a bit so CSM and Secure Boot were next to each other.
    In actuality you need to scroll down a lot to see Secure Boot...

    In order to be able to disable CSM and still be able to boot... you need to make sure your Windows disk is GPT.
    You can check that like this...

    If your Windows disk shows an asterisk under GPT, then you can safely disable CSM.

    Thanks everyone for the great replies. What is the importance of these settings? I mean, is having CSM enabled better than having it not enabled? If I disable CSM in the BIOS will this screw up anything on the system? I'd read somewhere that the system drives need to be set to MBR or GPT. Is this something I have to do first, or will it happen automatically when I disable CSM?

    I've also read that GPT is superior to MBR. In a tutorial I found it said to open disk management and check what partition style the main drive is: "Under the "Partition style" field, if the field reads GUID Partition Table (GPT), the drive does not need conversion, but if you see the Master Boot Record (MBR) label, you will need to use the conversion tool."

    I checked this and my secondary drive which is just for storage is listed as "GUID Partition Table (GPT)", but the main C drive is listed as "Master Boot Record (MBR)".

    So even if I don't install Win 11 would it be better for my system if I converted the C drive to GPT?

    csm provides support for os such as win7.

    but the main C drive is listed as "Master Boot Record (MBR)".
    gpt and mbr are partitioning styles set up when initializing the disk.

    it is possible to convert partition style using tools such as mbr2gpt ( though it it is quite picky ) or aomei partition assistant ( pro version and up ) or diskgenius free version - which involves a couple of manual steps and is more flexible.

    That's up to you. GPT is "better".
    The problem here is... if you disable "your" CSM... you "might " not be able to boot Windows until you re-enable it.

    UEFI BIOS goes with GPT disks (Windows is bootable).
    Regular (non-UEFI BIOS) foes with MBR disks (Windows is bootable).

    There's a tutorial for converting a disk from MBR to GPT without data loss, as mentioned by @SIW2

    Man, that stuff is way over my head. First, I don't have Windows PE and I'm not sure which one to download off the Microsoft site. Second. I don't even understand it enough to feel comfortable using it.
