Windows 8 Custom Boot Logo

Ok, so I want to make Custom Windows 8 Boot Logo’s, and I cannot find any information online about replacing the built in one. This is intended to represent my research into this. Ok, so here is what I know: The file that stores the image is at C:\Windows\Boot\Resources\bootres.dll If you use Resource Hacker, you will find under RCData – 1 – 1033 a bunch of binary. Right click on RCData, and save all. Of the files produced, you will find one that’s called RCData_1.bin. This is actually a WIM file, so rename it to RCData_1.wim and mount it (I used a tool called gimagex). Inside (After you grant yourself access) you will find the boot logo. The Boot logo is actually 6 images. Winlogo1.bmp 93x108 24 bit Winlogo2.bmp 118x135 24 bit Winlogo3.bmp 149x172 24 bit Winlogo3n.bmp 115x172 24bit Winlogo4.bmp 275x321 24 bit Winlogo5.bmp 370x426 24 bit They are all set as read only, so to edit them, Select them all and un-check Read Only. Up to this point, I am pretty sure I have everything proper, but here is how I proceed (It does not work). I opened each image with Photoshop and placed the number of the image on it (I wanted to know what image my computer was actually using, so I wouldn’t have to edit them all with special pictures). I then make all the images Read only again, and write the changes to the WIM. I rename the WIM back to bin. Then I use Resource Hacker to put the images back into the bootres.dll and place it back in the correct location (C:\Windows\Boot\Resources\bootres.dll). When I reboot, I expect to see the image with the number, but All I see is a black screen with the spinner. So, does anyone else have any suggestions? I have tried signing bootres.dll, but all I get from that for me is "Error: Failed to sign ‘bootres.dll’: %1 is not a valid Win32 application (2147942593)" using Signer from coderforlife.com. If someone can work out a good way to do this that works, I’ll write a program to automate the process, including resizing pictures etc. Just a side note, the bootres.dll from the new Windows 8.1 Preview works with current Windows 8, so we have more than one OS that will be customizable with this. (And you can get the 8.1 boot logo in 8!) Oh, and The Windows 8.1 Preview makes Windows 8 look like a half-baked crap cake. For those of you that I know will go "Why would you want to, you only see it for 2 seconds anyway?" Go away, this is customization for customizations sake. (Unless you are going to help, in that case your welcome to help.) Warning: If you try this, you may not be able to boot again unless you put your computer into Test Mode. (My Video driver makes this necessary for me anyway, so meh.)
