edgerouter + netboot + tftp server

[wesk1]

Hello,

I'm running a TFTP server on my Ubuntu PC to store the netboot files, configured my edge router
using the tutorial from netboot for edge router users I have pxe.conf and open-space.conf in my router, so far it works but I get a message that some files are not found then it looks like it pulls a file from the netboot site

my question is what are the missing files used for, and for Windows, it asks for a URL to the installation files I was thinking of setting up a simple HTTP server on my Ubuntu PC with the files but which files do I need, how should the folder structure be?

Update: I found the files by following the self-hosting tutorial and running ansible-playbook cmd.
