I'm going in circles now after 48 hrs of attempts, so wondering if anyone has any insight for me.
I've been running a G3 iMac with External HD for storage and just purchased a G5 iMac (single core).
This is what I want:
1. To retain OS 10.5 that came with computer
2. To have OS 10.4+ to be the start up disk bootable from External HD partition
3. To be able to boot up OS 9+ from External HD partition so I can use my old graphics software.
What I've done:
Took an external HD and made 3 partitions
c. Backup storage
I used my old computer to link to the External HD to install OS software from original software disks.
The OS 10.4 partition boots up fine. The OS9.2 partition is nowhere to be found in the start up disk selection (System Preferences-->Startup disk).
Printing is also a problem as I'm told that when you print from Classic, you need to use a network.
Am I foolish to think that I can have two bootable drives on a partitioned External HD?
That's right, you can't boot into OS9 from your G5.
On the other hand, you can start Classic mode using the OS9 system folder on the external drive, but you have to boot into OS10.4 first. Once you've started OS10.4, then go to System Preferences and click on the "Classic" icon. You will then get a new window where you can select the system folder to use for OS9. Select the OS9 system folder on the external drive. If you try to run an OS9 application then "Classic" will start up and will try to run it. Keep in mind that this isn't the same as booting into OS9, but it will allow you to run many OS9 and older applications, with some limitations.
