Two partitions - main one running Mojave 10.14.6 - can't seem to put OS X 10.7 on the other

I've tried everything, with a fresh wipe of the drive I've created two partitions - one running the main working software as 10.14 and in the other I had hoped to put OS X 10.7 to run several legacy items. But everything I do still yields "This version of Mac OS X is too new to run "install Mac OS X" from Mac OS 10.7."" when I try to install 10.7 from the bootable USB (that works flawlessly with other computers.)

Am I SOL?

With thanks!

That iMac 5K 27” 2017 is supported on macOS 10.12.4 or 10.12.5, or later. That Mac will never boot OS X 10.7.

The only path to use that Mac is via a guest in a virtual machine, and getting there will likely still involve an older Mac as an intermediate download. Or restoring and booting a 10.7 backup. (Not unless the VM provides some way to emulate an older Mac that can run OS X 10.7 and can also then boot that emulated older Mac into OS X 10.7 Recovery, and I’ve not encountered a VM with that ability.)

This Mac is probably not supported with OS X 10.7, either directly, or due to a more recent firmware update.

Ponder that you did not include the specific model of Mac and the model year in your question, too.

Thank you for your response MrHoffman...and thanks for pointing that out. The iMac model is: iMac (Retina 5K, 27-inch, 2017) - I am running the latest Mojave in the main partition.
