So I've already partitioned my hard drive into two sections, one that I would like to run tiger on and the other leopard...I'm using a .dmg file to install leopard so I used a method utilizing disk utility that has me mount the image then restore it to the partition I want to install it on, but every time I try to restore it I get a message... "An error (16) occured while copying. (Resource Busy)" A few other times I tried it gave me different error messages but I can't remember what they are...and now my other partition I tried to restore it to appears as "Mac OS X Install DVD", the file name of the .dmg...help please!
