The exact model I am trying to restore is the iMac Intel 20"/2.1GHZ/1GB/250GB/SD/BT/AP - Model A1207 - EMC 2118
I have no disks, grey or otherwise that came with the machine. I assumed they were lost or never given to the current owners of the machine. They have a tendency to buy used models rather than new ones to save money (and yet here we are). I tore down the machine to inspect the hard drive, assuming it had failed and discovered it was a 2TB replacement. I removed it and put back in a 1TB drive and it tried to boot finally with the QFolder blinking.
I thought I was on the right track and sought out disks to reinstall the OS. This is definitely is EOL, but there are some great resources for outdated Mac disks. I managed to make a copy of 10.4.7 (2Z691-5859-A) from archive.org. It starts off great, Apple logo shows and the wheel turns... then NOPE. Not the right disk?

I am assuming I have the wrong disk to match the system, but I am at a loss and would like to know if there is a solution. Target disk mode works, but aside from building another disk using Firewire, any ideas?
I'm going to dig a little deeper and explore the install disk idea from The 8-Bit Guy: https://www.youtube.com/watch?v=ngJ9q9wHcS0
