The intro zone counts as the first stage. This is when Vader is summoning bot holograms at you. It tells you to push X to attack, but you can just use force skills instead. If you push X here, you will not get the achievement. For what it's worth, I did get mine in stage one, just mashing the Y button the whole way.
