We need more details. What drive are you using?
Unless you have a SH-162D or similar drive with the update firmware (many a tutorial on this) you will need to read the game using either the WXripper method or dumping the game via the xbox 360 drive (samsungs only)
See the stickies at the top of the forum for tutorials on these - sorry if this is obvious stuff, if it is, back to the first quesrion; drive?
