OK...so I received all my new goodies for the iMac today. Here is my dilemma.... I have this thing running Leopard and have no Tiger install disc. Swapping out the Hard drive is now going to be a giant PITA. I will have no real sure fire way to get it up and running after I swap the drive. Remember this is an 800mghz G4 so I have to use leopard assist to install OSX Leopard. I am attempting to clone the HD right now onto a small portable laptop drive, but as I do some more reading I see that it may not boot from the USB drive. This kinda kills the idea of cloning to USB, swapping drive booting from USB, and re cloning that onto new internal drive. I am just not real sure of how to go about this the least painful way....HALP..!!
