I want to perform a clean install on an iMac 1.9 GHz PPC G5...
This iMac came with System Install Discs (OS X Tiger 10.4.2)
It is currently running OS X Leopard 10.5.8 (PPC does not support Snow Leopard)...
The iMac will not read my Leopard DVD (Burned Copy...NOT Original)
Although, my MacBook (Intel) reads the DVD just fine...
The iMac also will not boot from this DVD when I hold C or Option...
So...
Where can I go from here?
The goal is to simply erase my iMac...
I want to give it to my parents to so they can use it...
Is there anyway to achieve a "like new" condition without this install disk?
The only alternative method I can think of is...
Perform a clean install with System Discs (Tiger 10.4.2)...
But if I do this I wouldn't be able to upgrade it back to Leopard...
Given that it currently will not read that burned DVD...
And I won't pay for a used/new Leopard 10.5 install disc...
WAY TOO MUCH MONEY...they sell for $200+
Thanks for the help...
Any thoughts or suggestions would be greatly appreciated...
