So, have you first gotten PXE boot/install to work with one of Debian's standard installation images? I set that all up some years ago, worked perfectly fine. And pretty sure I followed this wiki page for instructions/guide: https://wiki.debian.org/PXEBootInstall If you can get that to work perfectly fine without any issues, then all you have left to do is the customization of your image, at least presuming that's how you want to go about the customization. There are, of course, also other possible means, e.g. preseed, etc. and could pass such data via your PXE boot configuration, or possibly other means. I know at one point I had my PXE environment set up such that the booted client would bring me to a menu, and from there, I could then select which ISO image to boot. But I haven't used that environment in some years, so it would almost certainly need at least some updating on its configuration, and some of its data, etc. And, wiki page ... if something isn't fully correct there or needs updating, well, it's a wiki. :-) So one could generally fix/improve that.
