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 boot system switch {number | all}
Step 4
end

Purpose
Verify your entries.
The boot manual global command changes the setting of the
MANUAL_BOOT environment variable.
The next time you reboot the system, the switch is in boot loader
mode, shown by the switch: prompt. To boot the system, use the
boot filesystem:/file-url boot loader command.
For filesystem:, use flash: for the system board flash device.
•
For file-url, specify the path (directory) and the name of the
•
bootable image.
Filenames and directory names are case sensitive.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Configure the switch to boot a specific image in flash memory during the
next boot cycle.
For filesystem:, use flash: for the system board flash device.
•
For file-url, specify the path (directory) and the name of the bootable
•
image.
If you enter this command on a stack master, the specified software image
is loaded only on the stack master during the next boot cycle.
Filenames and directory names are case sensitive.
(Optional) Specify the switch members on which the system image is
loaded during the next boot cycle:
Use number to specify a stack member.
•
Use all to specify all stack members.
•
Return to privileged EXEC mode.
