a depth-first search of a directory, each encountered subdirectory is completely searched before
continuing the search in the original directory. However, you can specify a specific image to boot up.
Beginning in privileged EXEC mode, follow these steps to configure the switch to boot a specific image

To return to the default setting, use the no boot system global configuration command.
