first of all, win 7 does support changing the the logon screen, if that is what you mean by boot screen. i would guess that it is, because the actual bootscreen is only shown for a few seconds. so if this is the case, there is already a thread, called something like, why is my logon screen different... or something like that. in that thread, there are instructions to do it manually, or near the end, there is a program which does it automatically, when you make a choice. the program is called, "Win7LogonBackgroundChanger". you can google it, or search for it on here. hope this helps.
