Simply keep the original install as is and after copying to another
machine write a xorg.conf with the vesa driver as a starting point. We
could help you to do this.

It's impossible to keep it simpler than it already is ;).

This is easy to do, we could help you assuming the information usually
included to fstab shouldn't be al you need to know.

# lsb_release -d; head -4 /etc/fstab 
Description:	Ubuntu 16.04.1 LTS
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices

This is also not hard to do, we could help you with this, too.

IMO it's easy to explain. I just like to recommend to download an Ubuntu
(flavour) live media release 16.10 for systemd-nspawn usage, to adjust
the copied install to the new machine. A short explanation for the OP,
systemd-nspawn allows to run the copied install by the live media and
to fix things, if needed.
