Problem with battle field 3 on xbox jtag

Hello everyone, after I download Battlefield 3 and extracted its iso and put it in my Xbox external hdd (as I do with most games), when I launch it with freestyle it work normally and after, selected difficult level it is send a message say that (insert single player game Disk). I played (gears of war 3, driver san fran,…..) from hdd with no disk with no problem. What can I do with BF3 with this problem?

Thank you

 

the single player content is on the second disc so you should use iso2god with the second disc iso and place that on a usb using party buffalo or something otherwise when you launch BF3 from the extracted contents of either disc it will prompt you to put in the other disc or the disc you would have in the dvd tray.

 

ok but what is party buffalo
