[QUOTE="dtravis7, post: 990279, member: 8287"] Also if it still fails to boot off the 10.5 DVD, you might try a PRAM reset. It can't hurt and might help since you say the 10.5 DVD mounts on the desktop in 10.3. To reset the PRAM hold down Command+Option+P+R all at the same time right when you hear the startup sound and keep them down. Listen for 2 more startup sounds then release the 4 keys. Also try what Ketan said and run the installer from within 10.3 and it should ask to reboot. See if it then comes up in 10.5. Also you did say it was a black DVD. Just being sure it's not a 10.5 DVD that came with another Mac. [/QUOTE]
