Starting and stopping the system

Changing the startup process

Each time the computer is started, the system runs the boot program. Unless you give different instructions at the prompt, boot loads the default kernel program using the configuration values specified in the file /etc/default/boot on the default root filesystem. You can change the current boot process with your response to the prompt, or you can use the System Startup Manager to change the default configuration values for future boot operations. You can also edit the /etc/default/boot file to change these options manually.
