thats impossible. The boot screen lets you revert the drive before boot.ini is processed. You can't revert the drive after boot.ini is processed. If goback logging is disabled the boot screen will still pop up. If you are trying to shave off boot time getting rid of the boot screen, if you were able to at all, it wouldn't do anything as goback finds a start point in its logs while the boot screen is displayed, regardless if you want to revert or not.
