This post is to answer the question asked here today:
Let's say that your 4MLinux is installed on /dev/sda1. Boot the 4MLinux live CD or USB. Open terminal and execute:
Now boot 4MLinux from your hard disk drive. 4MLinux will say "Oh my God !" and it will repair itself within a few seconds :-) You will be asked for a new password.
4MLinux is the only distro, which will survive the "rm /etc/*" command executed by root. Do not try it unless you are running 4MLinux.
