Failed to boot winpe by ipxe: Enter bootmgr.exe with parameters at 0x2a390

No error is show in the image, so I'm assuming it just hangs, you could try to add the gui parameter to wimboot (or remove it if you already are using it) and see if that gives you something different, also you might want to test with adding the pause parameter, just to get a little bit more information about where it hangs.
