[howto] chainload wimboot

[Bowser]

Hello to everyone,

like the subject says I need to know if there is a way to chainload wimboot within an other bootloader.
The background of this question is that im currently writing my own bootloader that starts a WINPE over HTTP. In the last weeks I managed to start a bootmgfw.efi over PXE. And now I want to chainload the wimboot instead of the bootmgfw.efi and afterwarts let the wimboot start the WINPE over HTTP. Ist this possible? And what do I have to do?
I have no idea how to start with this and I hope someone of you could help me.

p.s. I'm very sorry but english is not my nativ language so please apologize if I did misspell some words.

Kind regards
Bowser
