Creating custom ISO on Windows

[hamstermandk]

My setup is that I have a Hyper-V for my Virtual machines.

I am running an Ubuntu server in one of the VM's but it was manually installed.
I am in the process of making an unattended installation of Ubuntu - automatically (in a PowerShell script).

I am doing this from a Windows.

I can create the ISO - make it bootable but it won't run the unattended installation.
I am suspecting that the ISO is not made probably and I have tried different tools.
Eg. mkisofs (for Windows).

If anyone have succeeded creating an unattended custom ISO for Ubuntu on Windows I would very much like to know how they did it.

I found out that there is really not much difference between Windows and Linux when creating the ISO.
Just need to remember to use

$Image.FileSystemsToCreate = 3

when using the New-IsoFile powershell function.
