    so my asus ranger vii m/b settings aren't stopping
    the external samsung M3 portable HD from interfering .

    So keep getting the error:
    bootmnger not found error
    CTRL-ALT-DELETE required

    Needless to say samsung and asus aren't supporting

    Change the boot order to boot from the installed HD first.

    Starts on page 3-44 of this manual:

    I've messed about with those boot settings till I'm blue in the face
    You's think it would be easy as I have a M.2 drive with the win 10 on it
    so disable USB and even SATA, don'r help me at all.

    It might help to know the diff between UEFI and legacy Prom though?

    I disable almost everything and POST still wants to boot from the external HDD.
