Ubuntu minimal server is a version that comes with the bare minimal to get Ubuntu going. No desktop interface and other packages that come with a full Ubuntu disc or ISO. The Minimal server ISO will download packages from online archives at installation.
Downloading packages at install time reduces the size of the ISO image as well as providing only the packages needed for installation. The mini ISO uses a text-based installer, making the image as compact as possible.
This is probably the best option for those wanting to install a clean Ubuntu server to run their applications. This brief tutorial shows students and new users how to install a Ubuntu 17.10 Minimal server version on your machine.
To install the server, you’ll need to download its ISO from online. The link below should take you to the download file.
After downloading, you may have to burn the ISO image to a blank CD/DVD. Then boot the server from it. If everything is right, you should see the boot screen below:

On the next screen is where you choose your location. This will be used to set your timezone.
Next, select No to detect your keyboard layout. It’s always good to manually choose the layout during the installation.
Then choose your keyboard layout and continue.
Next, select the layout matching your previous selection and continue.
On the next screen is where you type the system name or hostname. Type a name for your machine and continue.
On this screen is where you select the archive mirror to download Ubuntu packages from. Always select the archive closest to you for quicker download.
