Loading /boot/defaults/loader.con
The device in normal operation will not go into this prompt if the boot process is not interrupted.
If the device is in this prompt then we can simply press[Enter] and it will go ahead and run the loader.
If we have run any command on this prompt then we need to run the following command to run the loader
boot:/boot/loader
After the execution of this command the device will boot up as normal.
