Redhat Linux root user password reset (Works for basic installation)

Hey, It happened to me that I got a VM copy of an RHEL4 Operating system. But, I don't know the root password. I followed the following steps.. Here you go..

At RHEL start-up screen, press any key before it is going to load the OS.





Then it will give a start up menu, here you have to type 'a' once.











It will give you a prompt to edit the existing start up options. Here you have to append 'single' to the existing command







Then you will be entering the OS with '#' prompt. There you have to give the following command

# passwd root

Give the password as you like..











Gotcha is that..it works only for basic installation without any special configuration for password/boot loader.
