This will create a fully automatic installation of Ubuntu Desktop versions so you dont need a keyboard, mouse or a monitor to get it installed and configured. Tested on 17.10 and all previous releases under it.

Scripts are attached of my basic configuration I used that worked. Just change the passwords under root and user account and if you use /dev/sda it will work straight out of the box

download the Ubuntu Desktop iso from any ubuntu mirror site you want, it will probably work with other flavours of Ubuntu too but untested right now. Once you got it -

Mount Ubuntu ISO but this doesnt work all the versions

You will need to mount the ISO files so that you can edit the pertinent files.

mkdir -p /mnt/iso
mount -o loop ~/Downloads/ubuntu-16.04.1-desktop-amd64.iso /mnt/iso

Copy ISO Files

Now you need to copy the files in the mount location to a different directory so that you can edit them. /opt/ubuntuiso was good for me

mkdir -p /opt/ubuntuiso
cp -rT /mnt/iso /opt/ubuntuiso

Edit the txt.cfg File

Here we will edit the /opt/ubuntuiso/isolinux/txt.cfg file and customize our boot parameters to get a completely unattended install which will include a preseed file. Use any editor of your choice:

#default live
#label live
#  menu label ^Try Ubuntu without installing
#  kernel /casper/vmlinuz.efi
#  append  file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash ---
#label live-install
#  menu label ^Install Ubuntu
#  kernel /casper/vmlinuz.efi
#  append  file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity initrd=/casper/initrd.lz quiet splash ---
#label check
#  menu label ^Check disc for defects
#  kernel /casper/vmlinuz.efi
#  append  boot=casper integrity-check initrd=/casper/initrd.lz quiet splash ---
#label memtest
#  menu label Test ^memory
#  kernel /install/mt86plus
#label hd 
#  menu label ^Boot from first hard disk
#  localboot 0x80

default live-install
label live-install
  menu label ^Install Ubuntu
  kernel /casper/vmlinuz.efi
  append  file=/cdrom/ks.preseed auto=true priority=critical debian-installer/locale=en_US keyboard-configuration/layoutcode=us ubiquity/reboot=true languagechooser/language-name=English countrychooser/shortlist=US localechooser/supported-locales=en_US.UTF-8 boot=casper automatic-ubiquity initrd=/casper/initrd.lz quiet splash noprompt noshell ---

Create seed file to fully automate things. nano/vi/whatever editor create the file ks.preseed and place it in /opt/ubuntuiso

Create the iso with this command

mkisofs -D -r -V "UNATTENDED_UBUNTU" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o /tmp/ubuntu-desktop-unattended-install.iso /opt/ubuntuiso

Write the file that is now in /tmp/ubuntu-desktop-unattended-install.iso using dd or any tool that writes bootable isos (Etcher keeps giving warnings about being not bootable so i didnt bother with it)... it will install within minutes and have you up and running with absolutely no input at all

if you are having trouble installing it fully unattended and it gets stuck on the stupid WELCOME / Language Selection screen it may be because when you insert your USB stick, that gets assigned as /dev/sda rather than your actual internal hard drive which should be /dev/sda so you can place this in the seed file to fix it and ignore USB sticks altogether

# Due notably to potential USB sticks, the location of the MBR can not be
# determined safely in general, so this needs to be specified:

d-i grub-installer/bootdev  string /dev/sda

# To install to the first device (assuming it is not a USB stick):
#d-i grub-installer/bootdev  string default
