hey there. here my story; i tried to use boot camp on my macbook with Leopard to insall windows xp. i used an old cd i used to have for a long time...probably windows xp pro sp1. so after partitioning my hardrive and tryig to install it, it says that there was an error and the installation didnt work. i said "fine ill give up on it and buy a new windows." so i remove the partitioned drive and thought that would be the end of it. but THEN, everytime i open my mac, i get a black screen which says "no boot device detected, please insert cd blah blah" and i have to restart my macbook and hold the option key to open OS X (when i do so there is no other option than OS X) its anoying me and i wonder if you guys have any clue to how to fix this. thanks
