How to boot from CD and create backup file?

I used previous version of Ghost before.  The version 14 I bought few days ago doesn't have menu to create a backup of a partition when booted from the program CD.  The older version did. 

 

I have an unstable system that I would like to backup before it finally crashes.  I don't have luxury to install the program to back up from there.  Please help.  TIA.
