Installing a modern Linux distribution has become a surprisingly simple and evolved process from what it once was. For this walk-through we’ll use a VM. This is a simple straight forward process – when installing on a physical machine, there can often be many (frustrating) unexpected issues! The good news being that many issues you are likely to encounter have been documented and solved by others.
To begin lets acquire a copy of Centos 7:

As we are installing this in a VM, we can simply mount the ISO in our hyper-visor. For a physical installation, a tool such as Rufus can be using to transfer the acquired ISO to a USB stick, from which the target machine can be booted from.
Boot your target installation machine with a mounted ISO / Burned DVD or USB stick. The installer will present you with the following greeting. Select your localized options and proceed.
For most installations, where preservation of data is not necessary, allow the installer to automatically partition your selected target drive.
As we are using the minimal installation ISO, we have no options – minimal install it is! Note – any packages / options can be installed post install.
It is advisable to enable the network configuration before installation, as it will save a step later on. See nmtui.
At this stage you are ready to proceed with installation after completing all pre-validation steps.
After completing what could be a lengthy amount of install time, you will be greeted with the completion screen. Make sure you have created a root password and an optional local user account. Click reboot and your new install is ready to run.
