I bought my imac 2008 with grey leopard install discs, I don't have them anymore.

I have a retail version of Leopard.

I can start the retail leopard disc with imac 2008 and imac G4.

So
I make a new partition on my imac 2008?
Install leopard with imac 2008 on new partition iMac 2008 or new partition imac G4? with the install DVD.

Once it is installed I do the updates with leopard on the 2008 imac, not the imac G4?

on my imac 2008 i open disk utility and format the G4 HD with HFS+ (what is AMP?) with target disk mode.

When format is completed, I start CarbonCopyCloner and clone new leopard partition from imac 2008 on G4 imac.
Once finished, I start G4 in leopard.

Delete the extra partition on the 2008 imac..



can you be more specific with steps? :)


Do you have the reinstallation disc for your 2008 iMac? If you do, you can still get Leopard onto that G4 iMac. Using Disk Utility on the 2008 iMac, make another partition on its hard drive. Install Leopard onto that partition using its reinstallation DVD. The retail Leopard DVD will not work as it is too old to support that iMac. Once the installation is complete, run Software Update and update everything. Trust me, update Leopard on the 2008 iMac instead of the G4. In Disk Utility on the 2008 iMac format the G4's hard drive with HFS+ and AMP with it in Target Disk Mode. When the formatting is complete, start CarbonCopyCloner and clone the new Leopard partition from the 2008 iMac onto the G4 iMac. Once that is done, you can startup the G4 into Leopard and remove the extra Leopard partition from the 2008 iMac.
 
The Leopard retail disc may not work on your 2008 iMac, but you can try installing it onto a new partition on it.
 
The retail disc does work on my imac 2008! :)

But if I install leopard with my imac 2008 on a second partition on the imac 2008 hard drive... and then update is... How can a PPC read an intel based leopard?

Leopard is a universal operating system. The only thing that makes them boot up on PowerPC Macs is the APM partition scheme on the boot drive. Intell Macs don't care if the drive is APM or GUID and will boot from it without a problem. If you copy the contents of the disc from one Mac to the other and making sure the target Mac has the proper partition scheme, it'll boot on it.
 
Older Mac combo and super drives have troubles with DVD+ or DVD- media I can't remember which one it is. They only read/write to one of the standards though. If it really bothers you you can try swapping the DVD drive out for a newer and faster model.

If you had the original hardware diagnostics DVD that came with the machine you could run a hardware test of the RAM/HDD.

I'm actually almost certain its nothing more than a DVD drive problem, try target disk mode to do the install.
