Windows 11
I have tried to prepare my Gigabyte B360M DS3H Motherboard for Windows 11 several times. each time the process fails and I'm left with a Clean Windows 10 installation. Today I tried again.I checked I have TPM on the PC . I converted the disc file system from MBR to GPT, using Easeus Partition Master. The PC refused to boot and diplayed the attached message telling me a device was not attached. I restared the PC and entered the BIOS setting but am unable to locate any sign of a Secure Boot setting. So, I am now left with a PC that will not allow me to install Windows 11 and am faced with having to reformat the disc to MBR format , and reinstll my applications, again. The Gigabyte website states that the motherboard is Windowss 11 compatable. how can i change to Windows 11. please?

Does this help?
Also, could you please update your system specs with the correct Motherboard and CPU models. Thanks

I actually don’t see Secure Boot on your Motherboard BIOS Settings. I believe you would need to add a TPM module. I believe the Intel firmware TPM is PTT.
Create the ISO using RUFUS, bypass the need for TPM.

Here’s some info

That motherboard supports 8th gen and 9th gen Intel processors. They included TPM 2.0 capability on the chip.

I installed Win11 without Secure Boot enabled. Truthfully, I just didn't think of it, and I did absolutely nothing to bypass any requirements, I went right from the Microsoft playbook. However, I see in the Event Viewer that Secure Boot fails, so I need to enable that one of these days. :-)

The MB must be able to set secure boot but isn't required to be enabled to install Win 10 & 11.

When you converted the disc file system from MBR to GPT using Easeus Partition Master did it created the EFI partition with the boot manager on it?
The main problem is that those applications just convert the drive from MBR to GPT but don't create the EFI partition with the boot manager on it.
If it is the case you must convert the old System partition to a EFI partition. Easy task.
Boot from a Win 10 or Win 11 installation drive and at the Windows Setup screen, press Shift+F10 simultaneously to open a command line prompt and type:
diskpart
list disk <- note the disk number of the drive containing your Windows partition
select disk # <- replace # with the drive identified above
list par
Exit

With a cel phone tate a picture and attach here so we can understand your drive

Hi.

Boot into your BIOS and set "CSM Support" to disabled and "Storage Boot Option Control" to UEFI. This will enable your PC to boot to UEFI installation of Windows 11. Now you should be able to boot to UEFI Window 11 bootable media.

That isn't required. Edit: I miss read suatcini54 Post.
To install as UEFI - GPT it should be disabled.
CSM is to use Legacy boot instead of UEFI.

You can also enable TPM functionality for your Windows 11 by enabling Intell PTT in your BIOS.

Hope this info is satisfactory for configuring your BIOS for Secure Boot environment and installing Windows 11 as UEFI system.

Hi.

My knowledge comes from my motherboard manual and it reads that CSM must be disabled to enable Secure Boot.

I am sorry if your motherboard manual and your experience tell differently. My Secure Boot knowledge is limited to my motherboard.

I am sorry if your motherboard manual and your experience tell differently. My Secure Boot knowledge is limited to my motherboard.
I miss read your post #7. I'm sorry. You're correct
The correct is CSM must be disabled to enable Secure Boot

But the main reason the OP can't boot is because he converted the drive with the wrong tool and now he can't boot.
Secure boot doesn't need be enabled to boot Win 10 or Win 11.

Windows 10 doesn’t care about secure boot so.... install using a UEFI disk in Win 10.... if that’s how you need to get it working...
