    I already have "Windows 8/10" selected under "Windows 8/10" features. I'm using a 2TB mechanical drive, no SSD.
    Disable that setting.

    Could you please explain why? Gigabyte told me twice to keep that set to "Windows 8/10" if I'm installing Windows 10. Very confused here now. I can't believe it's this confusing to set my motherboard for UEFI properly for windows 10 installation. I appreciate the advice. I'm just confused here.

    According to this thread I should keep "Windows 8/10" selected. I have my settings all set to match those recommended in this thread. With these settings my PC keeps rebooting to Bios. Is this because my Windows 10 USB thumb drive isn't inserted yet? Is that why the PC keeps booting to the UEFI/BIOS?

    Hi,

    A snippet from the MB manual:

    CSM Support Enables or disables UEFI CSM (Compatibility Support Module) to support a legacy PC boot process. Enabled Enables UEFI CSM. (Default) Disabled Disables UEFI CSM and supports UEFI BIOS boot process only. This item is configurable only when Windows 8/10 Features is set to Window
    So yes, by disabling "Windows 8/10 Features" it should then automatically be set to UEFI only.
    Pls. insert your installation media and reboot. It should launch setup as there is no OS on the HDD.

    Cheers,

    You have to have the Windows 10 USB flash drive inserted when you power on your computer if you want to be able to boot from it.

    I suggest you install first and later on we can check if we can re-enable secure boot. As it is now, it's totally irrelevant since you don't have any OS on the disk yet anyhow.

    I just wanted to be sure I am installing it in UEFI mode. I don't want to try installing with the wrong settings.

    With my settings matching this thread I get the reboot loop to the BIOS. That's why I'm confused.

    If you install it in legacy mode, it's not the end of the world. You wasted 1/2 hour on the install, figure out what you have to change, delete the partitions on the hard drive and try again.

    Hi,

    With no bootable media present that's to be expected.
