I need to run the Classic environment, and have an old iMac G5 which I'm trying to use. The trouble is that it has 10.5 installed on it. I have all the install disks for 10.4, but the Mac won't boot from them. It acknowledges the disk, then after a few minutes I get the 'No Entry' sign.

 

(I've set up a separate partition to try to install 10.4 onto, but without success.)

 

This should work, shouldn't it? What's going on?
