I am not a tech savy person, this is my first pc and I really don't understand the innerworkings. My computer currently boots with Legacy and its needs to become UEFI for secure boot to work and I know that I need to turn MBR to GPT. I went to the command prompt and typed in mbr2gpt.exe /validate and it says "This app cannot run on your PC". I am really just blind to this whole situation I have no idea what I am supposed to be doing I have just been frustratingly googling questions and trying to piece it all together. Any help would be very much appreciated.

    I can help you with that. Here are the steps on how to go from Legacy to UEFI so you can enable secure boot and update to Windows 11:

    1. Check your computer's specifications. Make sure that your computer supports UEFI. You can check your computer's specifications by looking at the manufacturer's website or by opening the System Information window in Windows.
    2. Back up your data. Before you make any changes to your computer's settings, it's always a good idea to back up your data. This way, you can restore your data if anything goes wrong.
    3. Restart your computer. When your computer starts up, press the appropriate key to enter the BIOS or UEFI settings. The key you need to press will vary depending on your computer's manufacturer.
    4. Change the boot mode to UEFI. In the BIOS or UEFI settings, find the boot mode option and change it to UEFI.
    5. Save the settings and exit the BIOS or UEFI. Once you've changed the boot mode to UEFI, save the settings and exit the BIOS or UEFI.
    6. Enable secure boot. Once your computer has booted into UEFI, find the secure boot option and enable it.
    7. Update to Windows 11. Once you've enabled secure boot, you can update to Windows 11.

    Here are some additional tips for going from Legacy to UEFI:

    • If you're not sure how to change the boot mode or enable secure boot, consult your computer's manual or contact the manufacturer for support.
    • If you have any third-party drivers installed, they may not be compatible with UEFI. You may need to update or reinstall these drivers after you change the boot mode.

    Hi DavidVandiver1,

    I'm Sumit, here to answer your query at the Microsoft Community.

    I wonder if you have a 32-bit OS. Try it using WinRE:

    https://answers.microsoft.com/en-us/windows/for...

    To boot to WinRE, from where Windows can trigger the MBR2GPT tool, please see the steps below:

    On the Lock screen, press and hold the Shift key while choosing Restart from the Power menu. Continue pressing the shift key until you see the Windows Recovery environment, asking you to select an option.

    Click Troubleshoot>Advanced options>Command Prompt.

    The computer would restart.

    Login to your account.

    Then run MBR2GPT command.

    Please keep us posted.
