Any good multiboot guides for legacy systems?

I'm trying to install MacOS catalina on my desktop

It's running an AMD FX-8350 though, meaning it doesn't have UEFI. I've been able to find multiboot guides for UEFI systems, but none for DuetPKG legacy systems. Is there a guide for legacy?

My plan drive wise is to split one my 1tb drives between windows and linux and give the other to macOS
