Last night, i decided to be a complete smartass and attempt to install Leopard on my system (Tiger 10.4.11). it backfired. i mounted leopard in disk utility, it then appeared in system preferences as an option to boot up in, i then clicked Leopard 10.5.8 and locked the preferences and proceeded to restart the system. The system, on its first reboot, booted back into Tiger, I then rebooted again, this time the terminal appeared with a flickering screen index reading : dyld : library not loaded (pictures attached with post). I now have no idea what to do. I went into open firmware and attempted to boot from the original USB which Leopard was stored on, not happening. Since then i have tried to boot and the hard drives spin for a second then nothing. I'm not familiar with computer speak and I'm just asking for any basic instructions on how i can get the OS to boot up, if possible at all. I also have an emac and was thinking maybe there was some way i could open the ibook in target disk mode with a firewire connection and somehow boot and repair through the emac, again, i've no idea how that would work. Any suggestions would be greatly appreciated.
