Do you want best practices to to get FOG to deploy to this system? The answer is pretty different.
If you want FOG to deploy to this system then you can either use FOG 1.2.0 stable (with current kernels) or deploy FOG 1.2.0 trun (which is a dev release of the soon to be FOG 1.3.0). You can use FOG 1.2.0 stable (I’ll assume what you have installed already??). That will work with win7 no problem. If you want to deploy win10, gpt disks, or to a uefi system you will need to be on the trunk release.
We can go into best practices once its clear what you are shooting for.
