Abstract
A method and system provides for booting a computer system after configuration data becomes unusable. One method and system provides for booting the computer system from a set of configuration data that last booted the system properly. An embodiment is directed to attempting to boot the computer system from a first set of configuration data, and, if the attempt is unsuccessful, automatically booting the computer system using the second set of configuration data which successfully booted the computer system and was previously stored. In response to a successful boot of the computer system using the first set of configuration data, an embodiment is directed to updating second set of configuration data so that it is equivalent to the first set of configuration data as the second set of configuration data that successfully booted the computer system.
