ipxe usb only + wimboot

Don't change which partition is bootable.

As you have read on the error page you have to have an open interface for it to bind to, you can do this with ifopen as long as there is an interface.
For PCBIOS file:// does not work.

Using iPXE for local boots are painful, and is not the goal of iPXE since it adds to complexity.
One workaround could be to build the USB enabled version of iPXE with rndis support, and use an USB tethered phone as the "server"

For just USB without network I can not recommend using iPXE
