Disable Boot Logo in IoT

NeilS 1 Reputation point

I would like to disable the Windows logo during boot of IoT when building a new OS image. (Ideally i would like to change it to a custom mage, but that is another question).

I am able to do it at runtime via bcdedit, setting bootuxdisable to on.

There are steps in https://learn.microsoft.com/en-us/windows-hardware/manufacture/iot/oscustomizations, chapter BCD Settings, detailing how to disable the Boot Progress Animation Circle (which do not appear to actually work, as the animation still appears) by adding the CUSTOM_BCD feature to the image. I can see from the generated bcd that it has taken effect (the setting "nobootuxprogress" is set to "Yes").

Is there a WellKnownType that corresponds to the "bootuxdisable" bcd option? Is there a list of WellKnownTypes anywhere?

Many thanks

    Hi @NeilS ,

    Here is a similar thread: https://www.raspberrypi.org/forums/viewtopic.php?t=118442#p804313
    The main process is as follows:
    bcdedit /set quietboot on
    bcdedit /set bootux Disabled
    bcdedit /set bootuxdisabled on
    And here is a another method about registry: https://itectec.com/superuser/hide-the-logon-screen-windows-10-iot/

    How about placing the suggested bcdedit calls into one of the startup scripts? oemcustomization.cmd
