Read something a bit. Says about modifying bootres.dll in C:\Windows\Boot\Resources
yh that's what reminds me of how it's done in linux, you can simply access the resources used by the system during startup like the splash screen, simply edit it in GIMP, save it and you are done. The stuff you have to do in windows to make this work doesn't seem too sketchy in fairness, but the fact that the splash logo is pulled from your MOBO, by proxy means you at some point will need to edit your UEFI, which is where the danger starts.
