    Hello all, here is my question. I'm trying to revive a powermac G5 DP 2.0ghz that it bought online for nothing. The mac was sold to me without a HD, that i bought on the side. After numerous trials caused by the infamous ram/logicboard issue, i finally got to starting the system up and managed to get the system booting.

    now here is the issue: obviously i need to install mac osx 10.5 Leopard from scratch, as the new HD is formatted. But how do I do that? The mac starts up and reaches this first screen. I have a bootable usb image and when i use that to boot the mac gets stuck to this screen. I can click on the right arrow but nothing happens... any idea on what to do?

    apologies for some possible errors.. im quite new to mac world

    Things you need;
    1. Leopard/Tiger install DVD
    2. The HDD should be formatted as APM not GUID not MBR. This can be done thru Disk Utility which is contained on the Mac OSX install Disk. You will have a hard time booting from the USB image. There are topics here that you can read to get some information on how to boot from USB using Open Firmware.

    As Nameci says above it is possible to boot from USB but you need to go into Open Firmware to do so.
    If you have another Mac restore that USB drive to a DVD, best way is to use Carbon Copy cloner to do so.
    The better way would be to restore to a Firewire HD, these are bootable.
    Leopard on DVD/CD is expensive, just look on Ebay, they are more expensive then the Snow Leopard follow up OS.

    The problem here is he can't find the disk identifier which is mentioned in point #2 in that link, he does not have a working OS X environment so no Disk Utility.

    Yes he can. It will be listed as DiskxSx. Or a usb as USBxSx

    Can you please be more specific, I just tried this in terminal, no dice.

    Thanks

    Edit: I just looked on google, got to a page, what I want to know is the OF command to see which disks are available.

    Edit again: I think I found my own answer using diskutil list .
