Is there a way to change to boot screen animation to a custom image or screen on Windows 8?
So far I have not seen a solution where you can change the boot animation. There are changes you can make to the boot screen but replacing it isn't currently possible.
Here's a tool to help: http://www.wesnext.com/visual-boot-experience/
Step 1: Open Windows Explorer, navigate to C:\Windows\Boot folder. Here, “C” is your Windows 8 drive letter.
Step 2: Open Resources folder, rename bootres.dll file to bootresbackup.dll.
Step 3: Copy your new bootres.dll file to C:\Boot\Resources folder.Reboot your PC to see the new boot screen.
