Self-boot to non-self-boot?????

Can i change a self-boot backup disc to a non-self-boot disc? and how?

My problem is, i can copy every DC backup disc,wich ####ts with Utopia Boot disc! No problem with Clone-CD oder Discjuggler or BlindRead/BlindWrite!! But every Time i wanna copy a self-boot disk, it fails!!
now i wanna know why? and how can change into non-self-B., if it works(cause i´ve seen, DAYTONA 2001 only 1 audio file was shown)
Please help!!!
