Before you all freak out I got this game off of my friend.

See my friend just bought FFVIII for PC and I wanted it, but am extreamly poor. So we IMG'ed his Disc via Alcohol 120%. Once I did that I mounted the IMG file on a virtual drive, but the game keeps telling me Insert Disc 1.

So I'm completely confused as is to what to do. I know the sane thing to do would be to burn it or buy my own copy, but I have this at the moment and I'm frustrated.
