@Junkhacker
Thank you for answering me so far
Yes I want to do it by modifying the ipxe menu.
The problem is that I couldn’t find a tutorial, or documentation to change the menu order and add a line to the menu to deploy an FOG image without a password .
Can you redirect me to this tutorial and/or documentation ?

@Junkhacker

Okay, maybe I wasn’t clear.
The objective is to directly master a computer, without having to record it in fog.
Typically I want to initialize fog so that it deploys an image directly when I boot in pxe without the anregistered, without authenticating myself to select the image.
So even if fog doesn’t know the computer it directly starts the deployment of the image, and the only operation I have to do on the machine is to start it in pxe

@Junkhacker The objective is that my fog server can capture images. And that the first option of the ipxe menu deploys a fog image chosen upstream. So I record a fog image, and I quickly deploy this image on hundreds of computers just by pressing F12 each time

I would like some help to modify my ipxe menu on fog. In order to directly launch a fog image.
I did not find much on the web …
Thanks in advance
