What can I do now?
Clearly you knew what you were doing when you installed Monterey, so why is installing an earlier, supported version of OS X proving a problem?
Snow Leopard comes on a retail DVD and is the way to go if you wish to restore your iMac to its original state.
Okay, IIRC, if you have so deeply cleaned the main drive that the Recovery partition has gone, you would then put your DVD in the drive and press "C" as the computer reboots. The other way is to hold the "Alt" key as the system boots to bring up the disk selection menu.
You can clear the PRAM to restore defaults by pressing and holding the Option, Command, P, and R buttons during boot.
