commands will initialize the flash file system, and finish loading the operating system

Step 5 Initialize the flash file system:

switch# rename flash:
config.text.old
flash:
config.text

switch# copy flash:
config.text
system:

Source filename [config.text]?
Destination filename [running-config]?
Press Return in response to the confirmation prompts.
The configuration file is now reloaded, and you can use the following normal commands to change the
password.
