help with xecuter 2

alright so i got this xbox from my cuzin with xecuter 2. and then tonight i went and tried to hook up xboxb live and when i went to configure everything for the internet it wouldn't go back to the start up menu for the xecuter2 it just goes to the orignal xbox. anyone know how to get the xecuter2 running again

 

well instead of pushing the eject button i think push the power button aka little button.

 

i have done it that multiple times and when the xbox starts up it still xecuter2 down at the bottom but it still goes to the orignol xbox startup
