    Gotcha.

    Okay, so I just finished the install. It boots fine now straight to Windows 10 with Windows 8/10 mode selected in the UEFI /BIOS, CSM disabled and Secure Boot enabled. The only thing that confused me is I clicked "next" at the prompt to select a drive instead of "new", and it went right to installing. I'm guessing that it created all the necessary partitions?

    How can I confirm now that it installed in UEFI mode?

    And one other quick question - I have all my motherboard drivers already downloaded from Gigabyte's site, along with their APP Center software. But I see the motherboard also has an xpress install option, where I can have it install all necessary drivers and I can select which software to install. Does that work as expected or is it safer/better to manually install the drivers using the exe. files I downloaded from Gigabyte?

    I always install manually because my Motherboard drivers DVD installs Norton Security Suite and other software I don't want or use.

    Hi,

    How can I confirm now that it installed in UEFI mode?
    I'm pretty sure it did but one way to check it is to open a command prompt (admin) and run the following commands:

    Diskpart
    Lis dis

    The output will show the M2 drive and if you see an * at the end under GPT then you know for sure the install is UEFI.

    As for drivers, check first if you need to install OEM drivers as W10 is supporting ever more hardware.

    Yeah, I installed manually just to make sure. Device manager shows no red X marks so I guess I'm good to go.

    How can I confirm that Windows installed in UEFI mode? Is there a way to confirm that?

    Press Win + R keys to open a run dialog. Run msinfo32

    Somewhere about the 14th line down in the system summary is the bios mode.

    Hi,

    On the same page you can also see if secure boot is enabled or not. IMHO it will show enabled.

    Why do I always forget msinfo32 is still around.....

    Thanks for all the help.

    I just checked Secure Boot using "powershell confirm-SecureBootUEFI" at an elevated command prompt, and it said false. What can I do? I have it set to enabled in the BIOS. But when it is in the Bios it shows it is currently not running in Secure Boot.

    I ran msinfo32:

    BIOS Mode - UEFI
    Secure Boot State - Off


    In the BIOS, here's what's listed for Secure Boot:

    "Secure Boot can be enabled if 1.System running in User mode with enrolled Platform Key (PK) 2.CSM function is disabled"

    Secure Boot State: Disabled
    Secure Boot: Enabled
    Secure Boot Mode: Standard

    Solved:


    1. CSM Support: Never
    2. Secure Boot: Enabled
    3. Secure Boot Mode: Custom
    4. Key Management: Install default Secure Boot Keys


    This got Secure Boot working! So all is okay now. Thanks again to everyone for helping.
