I Think I Got It! Maybe. (A Possible "Workaround"?)

My Hardware:

MOTHERBOARD: AsRock Fatal1ty z370 Gaming ITX

PROCESSOR: Coffee Lake Core i5-8400 LGA 1151

OS DRIVE: Inland 240GB SSD 3.5"

REGULAR DRIVE: HGST 1TB 3.5" 7200 RPM

GRAPHICS: Internal Intel Graphics

I posted last week about using a Snow Leopard disk with the hardware above. I had an iBoot disk and ran into this issue before coming here and learning Snow Leopard really doesn't work with my latest hardware.

For reference

But why am I interested in making a Hackintosh? Because I originally owned a mac mini, whose logic board failed. Twice.

I just realized what this could mean. I could take the HD from the mac mini and somehow make it work with iBoot. Possibly.

Is this possible?

I hooked up the mac mini HD (with High Sierra) and was still unable to get it to work with iBoot. Then I realized iBoot was meant for Snow Leopard, and the HD is sierra.

TL/DR: Will the HD from my mac mini work with the proper program burned on disk?
