I am not quite sure what you mean.

If you want to run the installed version from the LiveCD, then that is probably still installed on the system and can be accessed from the CNC menu.

If you have downloaded the source, edited it, and recompiled, then you will have two alternative systems on your computer. (You can actually have as many as you want, as the compiled versions are "Run In Place", with all their files located in the directory where you compiled).

If you look in the emc-dev (or maybe linuscnc-dev) folder in the "scripts" folder then you will find a script called emc-environment, or linuxcn-environment. if you run that in a terminal window with . ./emc-dev/scripts/emc-environment (the dot space dot slash is important) then in the context of that window the emc (or linuxcnc with version 2,5) command will start and run your compiled version.
