Why doesn't halo 2 work my xbox 360 slim 4GB?

Question by Elena: Why doesn't halo 2 work my xbox 360 slim 4GB?
Good day!
I ordered a Halo 2 game, but when I insert the disc in my Xbox 360 Slim version 4GB it says: "You need too attach an Xbox 360 Hard Drive to play original Xbox games."

Wait, I have a 4GB Hard Drive already in the console, right? It should work then, I don't get what's the problem. Maybe 4GB just isn't enough to install this game? Please answer. Thanks in advance.
