Were you booting the machine or starting the game and logging into your game account ? If the latter, your game files typically wind up in the game folder, your user data winds up on your C:\ Partition, usually in the User Directory. This all gets set up when you run the install procedure.
The usual way peeps copy games from machine to machine (non-steam) is:
a) Install the game
b) Set up the user account
c) Copy the user files from machine to machine with USB stick or DVD
