Catalina Install Issue

Hi, I'm trying to setup a Hackintosh for the first time, I've managed to get to the Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina install on my main disk, but it won't let me select the disk I want to install to (or any disks) because "This version of macos . . . cannot be installed to this computer." I suspect that it is because it recognizes my ssd as an external drive rather than internal as it is actually. Can anyone help with this?
