Problems with boot disc, please help!!!

I recently D/L the Utopia boot disc(Nero image) and burned it to a CD. When I tried it on my Dreamcast however it did not work. It just brings me to the music player. If anyone can help me out here I would REALLY appreciate it [ the sooner the better ] Emailing me would be easier for me but if you just want to post a reply thas fine too. Thanks a lot!!!
