    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.



    You only need to do Option #1

    Convert Windows 10 from Legacy BIOS to UEFI without Data Loss

    I tried that and all I get is this:

    C:\Users\dougd>mbr2gpt /convert /allowfullOS

    EnablePrivilege: AdjustTokenPrivileges failed (Error:0x514)
    ERROR: Failed to enable backup/restore privileges.
    Check that you are running in a process with elevated privileges.

    You need to open the command prompt (as Admin).

    1. In Taskbar search box type: Cmd
    2. Then, at top left, right click on "Command Prompt" and choose Run as Administrator.

    Doh. That's what I thought so I tried it again and got this:

    C:\Windows\system32>mbr2gpt /convert /allowfullOS

    MBR2GPT will now attempt to convert the default book disk.
    If conversion is successful the disk can only be booted in GPT mode.
    These changes cannot be undone!

    MBR2GPT: Attempting to convert disk 1
    MBR2GPT: Retrieving layout of disk
    MBR2GPT: Validating layout, disk sector size is: 512 bytes
    MBR2GPT: Trying to shrink the OS partition
    MBR2GPT: Creating the EFI system partition
    MBR2GPT: Installing the new boot files
    MBR2GPT: Performing the layout conversion
    MBR2GPT: Migrating default boot entry
    MBR2GPT: Adding recovery boot entry
    MBR2GPT: Fixing drive letter mapping
    MBR2GPT: Conversion completed successfully
    Call WinReReapir to repair WinRE
    MBR2GPT: Failed to update ReAgent.xml, please try to manually disable and enable WinRE.
    MBR2GPT: Before the new system can boot properly you need to switch the firmware to boot to UEFI mode!

    C:\Windows\system32>

    Seems to have worked, but I don't know what that last part is under "Call WinReReapir to repair WinRE".

    So now I have to restart the PC and disable CSM? I'm not sure where I would switch the firmware to boot to UEFI. Where would I find that in the BIOS?

    With the command prompt still opened as Admin, type:

    reagentc /disable

    reagentc /enable



    ...one at a time



    Then, you'll need to reboot the computer... enter the BIOS and disable CSM.
    Then... enable Secure Boot

    Then hit F10 to save and exit the BIOS



    THEN... the PC Health check should say you're OK.

    Ok, I entered the lines as you said and got this:

    C:\Windows\system32> reagentc /disable
    REAGENTC.EXE: Windows RE is already disabled.


    C:\Windows\system32> reagentc /enable
    REAGENTC.EXE: Unable to update Boot Configuration Data.


    C:\Windows\system32>

    Don't worry about it. Do this...


    Then, you'll need to reboot the computer... enter the BIOS and disable CSM.
    Then... enable Secure Boot

    Then hit F10 to save and exit the BIOS



    Then right click and extract this .zip file to a New Folder on your desktop, and run: WhyNotWin11.exe

    Ok I restarted, disabled CSM and enabled Secure Boot in the BIOS. I was a little apprehensive about that file you posted, but I got it and ran the thing. It was kind of funny. I thought it was going to be some joke script or meme saying ":Why do you want Windows 11?" Lol

    If you get all GREEN boxes, like this.... you're good to go...

    If you DON'T get a GREEN box for TPM version, go back into the BIOS, and in the Tweaker section...
    enable AMD CPU fTPM ....then F10 to save and exit.

    Then... run WhyNotWin11.exe again.

    From your computer specs, that should be all you need to be Win 11 compatible.
