Windows 10: Enable secure boot on Gigabyte B450M DS3H for windows 11

My Windows 11 keeps failing. I ran the windows compatibility checker from Windows which told me I need to enable secure boot. I followed some youtube tutorials to enable secure book and TPM 2,0. Update still keeps failing. Ran a compatibility check from github WhyNotWin11 and it says Secure Boot is not actually enabled - my system info msconfig32 also says Secure Boot is off. But my CMOS says its on. Any thoughts?I've tried to upload some screenshots but the upload keeps failing, is there a trick to that?

Enable secure boot on Gigabyte B450M DS3H for windows 11

So I have looked everywhere and I could not find the answer to my question. I want to enable secure boot so I can install Windows 11, but it doesn't seem to work. I know I have to turn off CSM support to have access to the secure boot option. But when I try to save & exit my screen goes black and I have to cmos reset my motherboard. I have heard that this is a problem with some motherboards, and that it could be fixed by pluging your monitor directly into the motherboard or having a different usb type for keyboard and mouse (I am not so sure about the last one and haven't tried it). So the only thing I could do is cmos reset my motherboard to get my pc working normally again. According to Gigabyte this motherboard from the 400 series should be compatible with Windows 11 but then there is the secure boot thing so I was wondering if there is another way or a work around for this.

Pls tell me you don’t want to do that.

I upgraded from Win10 to Win11 , mobo B450M DSH3 Wifi (Gigabyte)

I just entered Windows, then restarted the computer, and it never worked again.

Now I have to buy a new motherboard.

Hope this help you.

Hi Sebas Gerritsen,

It is a big job to convert to UEFI, there are two methods.

1

You can try to convert the drive without data loss from MBR to GPT using the tool that Microsoft provide, then boot into BIOS and switch to UEFI Mode

Before you attempt to do this, please backup your personal files.

If that process works, you can set your BIOS to UEFI and enable Secure Boot

2

Backup your personal files, then clean install Windows 10 form a bootable USB and before doing that you will need to change BIOS to UEFI and convert the drive form MBR to GPT, which would wipe all data on the drive.
