Hello Community!
I’m trying to make an unattended installation of Ubuntu Mate 16.04.1, for this I want to add my own preseed file to ISO.
But it doesn’t work 
I tried editing the ISO using ISOMaster
My idea is to define users, partitions, location, language and some custom packages to be installed…
Could someone do it?
Regards,
Maurito
Ps: Sorry for my bad English
