Boot Disk For Mac [i need help]

I recently downloaded the Utopia BootDisk in Mac Format, but the problem is that the instructions were in french. I need help. I messed up one CD by writting the first track as Multitrack CD-ROM XA, and burned the Session. Then for track 2, i did the same thing, and burned the Session. Is there something i did wrong? I know i did, i dont think i was supposed to write the 2nd track as a session. But i still need help, can someone please help me?
