I think we need more than just better instructions here.

If you use automatic partitioning, there is also a "leap of faith" step where you have to hope that the installer does the right thing, but without any way of verifying it.

If you don't use automatic partitioning, it is because you already know enough to get past this stage.

In my opinion the most ideal scenario here would be a Windows based pre-installer - it runs the necessary checks that Fedora can be installed, sets up partitions and then reboot to finish installation.
