Changing Runlevels
In the following video I change runlevels from the command prompt using telinit, change the system default runlevel by editing /etc/inittab, and boot into a different runlevel from the Grub bootloader screen.
To change the default runlevel for a system, edit the /etc/inittab file.
The line to change is the line containing initdefault.
id:3:initdefault:
Change the 3 to the desired boot runlevel.
To temporarily change runlevels, use the telinit command.
To change the runlevel from the grub bootloader, select the kernel line to boot and hit "a" to append parameters to the kernel line.
In this case you would want to append the runlevel, S (for single user) or b (for emergency boot, which does not run any scripts and drops you to a root shell).
