I am restoring an ancient PowerPc iMac and I have a very peculiar situation. The iMac has a new ssd drive where Mac Os 9 is installed and works perfectly. I would like to install also 10.4 Tiger but the original install disks are long gone and burning a bootable disc seems impossible (I tried anything). The old 20GB hdd contains a perfectly working Tiger install and I could connect that HDD via USB because I have an adapter.
Is there any method that would allow me to end in a situation where I have both working and bootable operating systems on the new ssd?
Maybe copying the old disk to a partition on the new one?
