well you could just start the batch file and then when buildos loads uncheck everything and click play, when it says done (if you get no errors) close buildos and the batch file will continue creating your rom, then most kitchens load the rom update utility automatically. very simple!

if you get more adventurous go into the SYS folder and delete stuff like windowslive, entertainment, etc. I recommend rebuilding/reflashing after every edit so you know what causes it not to boot any more.
