game wont load after loading utopia CD

[beamer]

Maybe ill get slaughtered for this like so many on here but im a newbie to all this DC copy stuff and my head is spinning trying to dredge through all the slanging matches on here
Anyway .. Im copying image files( .cdi ) to CD using diskjuggler and when i put it in the console after successfully loading the Utopia Boot CD it just wont pick the game up at all. I have done a couple of games the same way which have worked.
i would absolutely love any help i can get ??
