Hi,
I have a power mac g5 its a few years old and I'm having trouble installing OS 10.5 leopard. When I turn on the computer i get a blinking ? folder that alternates showing a ? and a mac face, with a gray background. I tried putting in the start up disk ( ? folder doesn't appear with the start up disk) and it guides me through the installation steps, but it doesn't display a location to install the OS on. I also tried putting an external HD in and this does not appear as well. So, I went to disk utility and tried the figure out the problem. In disk utility, the internal hard drive is there, but not the external HD. I also tried switching Hard drive ports from a to b and this made no difference. IF you have any suggestion or solutions please post them. Thank you.

did you try using disk utility to erase your internal harddrive (thus also formats it) then installing leopard?

to say it was probably a failing HD, but you said you also tried a external, my only question I have for you is, are you sure its the retail disc?

If it's gray then you have the wrong disc.

The disk you would need would be Black with a big purple X in the middle. If you are using grey disks than it won't install.

This, unless he has the grey install disk that came with the unit.

G5's never shipped with 10.5.

I am using the 10.5 disk and it is a legit copy purchased from apple. When I boot up the computer with a the disk I would get a grey backround on the screen its no the disk

Should I try using a different OS disk?

Your OS disk is good. It sounds like your hard drive is dead.

The hard drive shows up in disk utility, but not as a install location. Could the hard drive be dead even if the computer recognizes it in disk utility?

And If the HD is dead should I get a new one or is there any way to repair it on the computer?

How did you format your HDD? It should be Mac OSX Extended Journaled.
