Why won't my PowerMac G5 2.0Ghz Dual Boot Leopard DVD?

I have a PowerMac G5 currently running Tiger OS X. I turn on the Powermac and it runs perfectly fine. I insert the Leopard Install DVD, and the Powermac reads it fine. It opens the CD and I select to boot Leopard, and restart the Mac. Then, the Powermac restarts and the screen shows a gray screen with the Apple logo in the middle. No spinning wheel appears under the logo. I wait for about 5 minutes, then the fans start blowing really loud. I have left it like this for a while and nothing ever happens. What should I do? Is there another way to install leopard? How can I fix this issue? Thanks!

After you install the base 10.5, download & install the 10.5.8 combo update at http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update

Does your DVD look like this?

A gray disc from another model Mac won't work.

Hello,

What is the 2z691-****-A number on the Disc?

Is it a Gray Machine specific disc?

Yes, it is the purple disc. And the PowerMac also meets the requirements for Leopard.

Does it show as a boot choice if you hold alt key at bootup?

Might it be this?

It would block usage of all the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option boot will show a lock, and Shift, as well as booting from anything but the Hard Drive.
