Install Mac OS X 10.5 Leopard via USB on PowerPC Macs (youtube) And if your iBook is the same, not working with the above USB method then you may need to try the Open Firmware approach to boot from USB: Install OSX 10.5 Leopard on Powerbook G4 (a1138) with a USB drive! WITH 10.5 LEOPARD IMAGE. Boot your Mac from your standard drive. Connect the external drive. Go to external drive OS X Install Data. Locate InstallESD.dmg disk image file — this is the file you need to reinstall Lion OS X.
My cd/dvd drive busted WHILE I was upgrading the OS to 10.5. Now I get the folder with the question mark when I start up, or a blank screen. Other than installing a new cd/dvd drive, how can I install the OS without the drive? I only have other Intel Macs to use, no PPC. I don't believe Firewire/Target disk will help much in this case will it? I don't need any data from the currently unreadable hard drive - luckily had transferred everything ahead of time, but also erased a backup OS 10.4 boot drive too soon.
Thanks,
Curtis
