This Windows 7 Boot Animation is Tony Stark's (a.k.a. Iron Man's) arc reactor powering up. The original image comes from apophis906 of droidforums.net, and the animation and formatting for Win7 are from me. Enjoy!
I ran the installer bit now I cannot load any other custom boot screen or uninstall this one because each time it says that it failed. I don't know if this is related to the custom boot screen but I can't uninstall or install anything else either and my internet stopped working, and my PC never shuts down. It just stays on the "Shutting Down..." screen.
That's very strange. It shouldn't have any effect on your Internet or your ability to install/uninstall anything. In fact, I can't see how it COULD affect that. As for saying the new boot screen installation failed, try going to Options->Restore Backups (in the boot updater program) and then you should be good to go to install a new one .
Try to boot up your computer. If it gets stuck in recovery, you need to follow the instructions on this page to fix it: [link]
After that, just use the .bs7 file instead of the installer and you should have no problems anymore.
