Browse All TopicsI want to install Leopard on my 17" (G4) Powerbook, i GB RAM.
It curently runs 10.4.11 from its internal drive.
I have the Leopard DVD, but the PB won't boot from it.
So I boot an Intel MINI from the DVD with the Powerbook connectied in Target Mode.
I get an error message "Reformat your Powerbook as GUID to boot an Intel machine".
Of course, the Powerbook is NOT an Intel machine (the MINI is) and wont boot if I foow its instructions.
Also, I cannot boot the PB from an external FW drive, non-GUID partitioned - with Leopard.
What can I do>

Does your PB have a DVD drive or just CD?
Will it boot from any other DVD or CD? (In other words, is there a problem with the optical drive?)
How are you trying to boot - by holding down the c key? What happens when you try to boot?
Have you tried booting by holding down the option key until the boot picker appears?
Have you tried resetting the PRAM by cold booting while holding down the command-option-p-r key combination until the computer chimes a third time?
Based on your description, you probably don't have a DVD drive in the Powerbook. You can check by going to the System Profiler and look at the disc burning info.
The easiest method to get around this would be to either get an external DVD drive to boot the powerbook from or find another PowerPC Mac to target mode to it and run the installer from that.
They only other method I've ever used in a situation like this was to directly image the hard drive using an existing image designed for that hard ware.
Homepup, I tried target mode as mentioned in my lst post. Please reread it.
Strung, I tried zapping pram before, and tried holding option. and picking the DVD. Didn;t try holding C.
I have a DVD drive. I can read the DVD fine. I can boot from other DVDs. Could it be the fact that Leopard is a dula layer DVD and the others are single?
You mentioned that you had tried target mode connected to an Intel-based Mac (please re-read your post). My suggestion was to target mode while connected to another Power-PC based Mac, if you have one available (please re-read my post). The installer looks at the local hardware of the computer running the install. It only sees the Powerbook as an attached, external hard drive and is telling you correctly that if you want to be able to boot the Intel Mac Mini from the attached external hard drive (i.e. Powerbook hard drive), you'll need to reformat it as GUID. You need to use the same processor types for the installer to perform as you'd want.
What hobowankenobi is suggesting would work as well, but the external hard drive would need to be formatted using the Apple Parition Map format, not GUID. If it is currently GUID, you'd have to erase the drive completely and reformat the partition using Disk Utility (Apple Partition Map is hidden under the Partition Options for the hard drive). Then you could use Disk Utility to create a secondary partition on that drive, make a .dmg of the installer disc, scan if for restore, then apply the disc image (.dmg file) to the partition you created. It would then be bootable and you could run the installation from that.
Afterwards, if you wanted to reclaim the space on your external drive (and had created it as a secondary (not primary) partition, you can use Disk Utility to remove it and resize the primary partition without harming any data.
Actually, I think you can do it using Firewire Target Disk Mode the other way around. Put the boot DVD in the Mini and boot the mini in target disk mode. Then connect the PB and use it to boot from the Mini's DVD drive. See the discussion in this thread and particularly the post by: da5idonimac on Tue, May 3 2005 at 11:44AM PDT:

Stung is correct. Done that before, totally forgot about it. Fastest thing with the gear you have listed.
As for my previous suggestion, all you need is that external drive/partition in the APM format......both Intel and PPC can boot it. Then clone the retail DVD to it, and it will be bootable - exact copy of DVD.
Boot to your DVD clone and install 10.5 on any Mac that will boot and install 10.5, both PPC and Intel. Just run Disk Utilty while booted to the DVD clone (just as you would while booted to the DVD), and initialize the internal drive with the correct format.......GUID in this case.

Is the Leopard disk a full retail install disk? If it is an OEM disk that came with another computer (the Mini, for instance) it won't boot on the G4. OEM Mac install disks generally will work only on the specific model of Mac that they came with.
