How can I remove the option “Press Spacebar for last known good config”?
A. The choice is hard coded into NT and therefore cannot be removed, however you can remove the functionality of what it does. Several sets of configuration information are stored in NT, the current configuration and one or more sets of old configuration that are known to work. What NT does in the registry is to point to the current configuration and also a link to one of the other sets. It is possible to change the link to the last known good config, thus pressing space at bootup will have no effect.
