Problems installing leopard on Mac Pro

[axototl]

I have one of the older G5 Mac Pro Quad core machines. When I tried installing my copy of Leopard OSX 10.5, the installer said there was a problem with the 'BaseSystem' and so I tried following the procedure for exiting back to OSX Tiger (my previous OS). Now I'm stuck in what I think is 'Terminal' and I can't get the Leopard disk out. Any suggestions? (I have looked at posts on ejecting CDs/DVDs and will try them when I get home, so thanks for that)

It's not a Mac Pro if it is a G5. Which is it?

Remove any third-party RAM until you can get it working again. Then reinstall the RAM after you get Leopard on there.

You need to clarify a few things.

You cannot have a G5 and a Mac Pro. It's one or the other.

Power Mac G5's pre-date the (Intel powered) Mac Pro. Which do you have?

Where did your Leopard discs come from?

Yes. Be sure that your Leopard disks are the retail copy, not some disks from another machine.
And yes, like others have said, we need to know your machine before diagnosing it.
