    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...

    I would read the DVD on your Intel Mac to a disk image file. I would then "restore" that disk image file to a USB stick that had been set up as partition table GUID, 1 partition HFS+. You should then be able to hold down option on your PPC Mac and be able to see the usb stick as one of your boot options, boot from it and do your install just as though you were using the DVD.

    Upon further investigation, perhaps you can't boot from usb. My cursory trip to google leads me to believe booting from USB was added beginning with 10.4.3 and your system shipped with 10.4.2 disks. Still it doesn't cost anything to try and your symptoms make it sound like you have a bad optical drive.

    I'm sure you can boot from a firewire drive. Do you have one of those? The same technique would apply. Partition it as GUID with at least one HFS+ partition which is "restored" from the disk image of your OS X DVD. The partition you restore to just has to be as big or larger than the image you are trying to restore. For instance, I restored a Lion boot image to an 8 gig USB stick when it wouldn't fit on a 4 gig USB stick.

    Lastly, if you believe the optical drive is good and it's just your DVD that is flaky, you could try burning yourself a fresh one assuming you can read the whole thing on your intel Mac.
