Recently I learned about making a custom boot screen for windows vista.
So here you go I share this information with you all.
How to install:
1. Navigate to c:windowssystem32en-US for english; NL-nl for Dutch and so on
2. Open the properties of the file “winload.exe.mui”, click on the security tab and choose advanced to set the ownership to “Users”
3. Now copy the chosen bootscreen from the package and replace it with the one in the system32en-US folder
4. Go to start > Run, and type “msconfig”
5. Choose the “boot” tab and enable “No GUI Boot”
6. Close msconfig and reboot your computer

Here you go, a brand new Vista BootScreen!
