|To change boot order in Ubuntu, open file /boot/grub/menu.lst and find in default section, change the number with boot menu order.
And to change run init level on Linux box, usually just changing the init default in /etc/inittab file and make it with your own run level that you want it. But in Ubuntu is a kind of different with other Linux, because Ubuntu runs in init level 2 and always runs under Xwindow. If you wanna change the login page become under console terminal (init level 3), you can make /etc/inittab file (on Ubuntu 8.04 there is no inittab file), so you can make it with this command :
# sudo gedit /etc/inittab
and type this script on the file :
save the file and exit.
And then rename /etc/rc3.d/S*0gdm file to /etc/rc3.d/K*0gdm and then restart the PC...
Root access on Ubuntu by default was locked, to activate it (if only you need it), type this command :
$ sudo bash
$ sudo su
and then change the password with your own password :
# passwd root
And walla..Root User is active..
To disactivate the root access again type this command :
$ sudo passwd -l root
