How to change boot picture in Windows 10 IoT?

Question

Is it possible to change the Windows logo during boot in Raspberry Pi 2 with Windows 10 IoT core?

My goal is to show just a splashscreen until the application is loading. I don't want to show Windows logo, but black screen is also bad idea (because of no feedback). In Windows 8/10 tablets I have seen branded boot screen, so it is possible there, but not sure how to achieve this in Windows 10 IoT.

According to Unbranded Boot Overview (Windows Embedded Standard 8):

The only supported way to replace the boot logo in Standard 8 with a custom logo is to modify the Boot Graphics Resource Table (BGRT) on a device that uses UEFI as the firmware interface. If your device uses the BGRT to include a custom logo, it is always displayed, and Unbranded Boot cannot suppress the custom logo.

I know it is for Windows Embedded, but that is the closest article I found about branding.

I don't know how the Raspberry Pi 2 booting works and whether it has UEFI or what. I guess it is at lower level.

Answer 1

Go to the Processes page on the IoT Utilities page and type these commands. It should disable the Windows logo.

1 - bcdedit /set quietboot on
2 - bcdedit /set bootux Disabled
3 - bcdedit /set bootuxdisabled on

Then restart RPI

Answer 2

For future Googlers, if you want to keep the spinner but lose the windows logo on Win10 IOT, run the following bcdedit command:

bcdedit /set {globalsettings} custom:16000067 true
