Fortunately, there are many good resources in the Internet. You will find my recommendations below.
1) Download the following items:
- InfraRecoder (if you wish to create live CD),
- UNetbootin (if you wish to create live USB),
- 4MLinux itself :-)
2) Watch this video to learn how to burn ISO with InfraRecoder, or follow this tutorial if you are going to use a live USB.
3) Boot your 4MLinux Live CD (or Live USB).
