G4 iBook has no OS
After a change of heart I've just re-assembled my white i-Book (G4, mid 2005, 1.33Ghz). Unfortunately I had wiped the drive prior to intended disposal. It powers up to the flashing '?' as there is no OS on the drive. How can I load one? The optical drive spins and I have an original copy of OS 10.5.4 but when I load it, it just spins and eventually stops.
I also have a 2012 iMac on Catalina, a superdrive, and a Firewire-USB adaptor on order. Would firewire Target Disc work and how would I configure it?
Any ideas?
