To disable manual booting, use the no boot manual global configuration command.

Booting a Specific Software Image

By default, the switch attempts to automatically boot the system using information in the BOOT
environment variable. If this variable is not set, the switch attempts to load and execute the first
executable image it can by performing a recursive, depth-first search throughout the Flash file system.
In 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.
Beginning in privileged EXEC mode, follow these steps to configure the switch to boot a specific image
during the next boot cycle:
Command
Step 1 configure terminal
Step 2
boot system filesystem:/file-url
Step 3
end
Step 4 show boot
Step 5
copy running-config startup-config
To return to the default setting, use the no boot system global configuration command.
