    Hello guys,

    just to explain the situation. I bought a Powermac G5 but I realized that it can't boot into OS. It shows only flashing question mark and finder logo. When I put CD into Mac and boot from CD there is Apple and circle rotating than after 30sec there is 'no entry' logo and circle is rotating forever. I suspected into HDD but when I changed it there was also the same problem. I don't know any solution more. Can you advice me?

    What year is your Power Mac G5, and what OS disk / version are you trying to boot from?

    the no entry sign with the spinning gear is typically

    "Cant find root device"

    which basically means OS X cant find its own HDD/DVD so i would check that the drive/cable is in good condition first (check stuff like slave master and CS jumpers)

    also its worth resetting the PRAM/PMU. you could also try and boot from USB

    which G5 do you own exactly? to start tho, restore the OS X installer to a USB stick of your choosing

    another easier option is to boot from FireWire if you have a Firewire storage device

    2004 or 2005? also where did you get your OS X installer disks?

    give me the exact specs of your G5 :)

    if its a 2005 G5 image OS X to a USB stick plug the USB stick in boot to Open Firmware and type: boot ud:,\\:tbxi

    1.6Ghz would be a PowerMac7,2 2003 model

    open the side door on the G5 right at the bottom edge is a sticker listing all the specs of the machine, if you can post a picture of that :)
