    Windows X (various flavours)

    Are you using cable USB keyboard?

    Possible causes of this are:
    - you are just pressing power button on PC. In windows select restart - this is real restart cycle in Windows 10. Normal power on /off is sometimes so quick you are not seeing BIOS options all.
    - user is putting PC to sleep instead power off
    - using wireless keyboard
    - pressing Backspace instead of "Delete" key

    Try these and report back

    edit: if non of the above works, try to clear CMOS (take out battery, or short circuit jumper - read manual)

This puts you into the Choose an option screen upon bootup, where you can "Use a device" to boot from a USB drive, network connection or DVD, or use the Troubleshoot option to attempt various forms of system update or repair (restore, image recovery, startup repair, command prompt, and startup settings changes).
    For access to UEFI, Brink has a tutorial on that subject that also works from inside the OS. I don't think you need the legacy BIOS info, given your mobo...
