This is my favorite boot screen I uses in my N900. and I loved to share it with you ..
the original video was taken from youtube and it appears to be the default boot screen for windows 8 .. i just changed the original sound in the video with the sound of windows 7 start up .. I also changed the the length of the sound file to be suitable with the video because the sound was ending a few seconds before the video ..
I hope u will like it .
