Several years ago we needed a simple method to get ubuntu on a desktop. What I did was the following.
- Using a testmachine I installed Ubuntu from a standard image (preferably an LTS version)
- I removed all software that I didn't want
- I installed all software needed, configured the desktop etc to what I thought was best
- For software like teamviewer that creates a unique ID for each machine, I did NOT start it to avoid creating that unique ID
Now I had this clean and "perfect" setup, I needed a way to get it on a new PC.
- I created an image using Clonezilla.
- I copied this image on a USB stick (or CD or DVD).
- I used a second USB stick to put clonezilla on, which can be started from that usb stick.
- I started the process of installing the ubuntu image from the stick using clonezilla
- This process includes how to start Clonezilla from CD or USB (editing bios etc)
- Once I had all steps in this process working without guessing what to do, I made screenshots of each step, put them in a Word/Writer document with instructions what keys to press etc.
- NB: I created the screenshots with my phone as I didn't know how to do this when using Clonezilla - ugly but it worked.
- When I had this installation manual ready, I tried it on another person, of he could do this without my help.
- When this worked, I created a PDF with the manual, two usb sticks per install, and gave it out to whoever needed it.
The result was a 10 minute installation process with a working Ubuntu desktop. The person who's going to do these installs has to be comfortable doing this, but after a while it's very easy.
You should use an LTS version to avoid having to do this all over after 18 months, when the this Ubuntu version is not updated anymore.
We used one type/brand of computer. Different computers probably have different bios screens, and that might be confusing to many people. So depending on this and on the person doing the install, this might be a problem.
I don't know if this helps you or not. Maybe you want a normal installation cd like the one you download. Like it or not, it's an option you can consider.
