I have: -one iMac with cracked screen -- currently being used via dual monitor setup -one new MacBook Pro (running Snow Leopard) -a legitimate, family pack DVD for Leopard I want to: -reformat the iMac and install Leopard on the iMac via Target Mode/firewire using the DVD drive on my MBP However, when I try to boot the MBP from the Leopard DVD, nothing happens. I know this is kind of a mess, but it's the only viable solution I have been able to come up with. I can't install Leopard on the iMac from the Leopard DVD because I can't see the screen (due to the huge crack on my iMac) and it does not show up on the extra monitor. Is there a way to safely force the MBP to boot from the Leopard install DVD? Thanks!
