    Do I have to change the Compatibility Support Mode for UEFI?


    Assuming I want to clean install Redstone 2 next month in UEFI mode, do I have to change the default settings below?

    How about the four 'Boot' settings below 'Launch CSM'?

    I believe you should see them change, after CSM is disabled..

    As CSM is legacy Support - once CSM disable> Legacy Support Disabled

    I intend to use the method mentioned in this post to convert MBR to GPT and then use the USB drive mentioned in this post to clean install Redstone 2 in UEFI mode.
    Does it work?
