Video example of the result

Hi,

Congrats for making HackBGRT available!

Would someone have a video showing the boot sequence after using HackBGRT?

It could be super useful for anyone who wants to use this tool (and modify UEFI settings), to be sure it is what we are looking for.

A boot sequence is often composed of ~ 10 different screens (BIOS POST, BIOS logo, Windows pre-login screen, etc.), so it would be interesting to see exactly which one of these screens HackBGRT is able to modify.

@Metabolix maybe? Thanks a lot in advance!

Maybe this is what you are looking for i just crrated a video of it on my Windows Handheld PC.

Take note that the install process on that video is different - i repackaged it and just created simple batch files for the install / uninstall.

Another video example - this one uses Clover and then Clover loads up HackBGRT and finally it goes to Windows - https://www.youtube.com/watch?v=M2CarrzNuN4

Thank you for your answer @Metabolix.

More precisely, which one of these screens can HackBGRT change?

Screen A:

Screen B:

Screen C:

Screen D:

screen B and screen C

Thanks @ryanrudolfoba.

Screen C can already be removed with:

bcdedit /set quietboot on
bcdedit /set bootux Disabled
bcdedit /set bootuxdisabled on

Do you know how to just remove Screen B without having to modify UEFI / without using HackBGRT?

HackBGRT does not draw anything, it just gives Windows boot loader an alternative image to draw. Obviously it's not possible to change the screen contents before the boot process without modifying the UEFI firmware somehow.
