Disable Boot Logo in IoT

Hi.
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://docs.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-7867,

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/

Best regards,
Seeya

Hi Seeya,

Thanks, but as I said I am already aware of that process, and that is during runtime, unless i'm missing something?

I need to have this all pre-set in the flash.ffu, and not have to run bcdedit command on every pi that I want to flash.

It seems there could be a method for doing this via the CUSTOM_BCD feature but no explanation that i can find of what options/WellKnownTypes can be configured in that way.

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