Did you burn it to a Cd-r or a Cdr-w?
It's best to put it on a cd-rw since the Xbox can't read cd-r's. Also, how did you create the disc, e.g. ISO or Data Burn method. Normally it's also a good idea to add a dummy file to the EvoX CD that your making, so that it will read a bit better in the Xbox. Thats my opinion anyway.
