There are 3 types of iso files –
Minimal includes a few basic packages and no desktop environment. DVD includes major packages updates and desktop environment. Everything includes all of the packages and it has the biggest size in all. Live images are also available for Gnome and KDE desktop environment.
In this installation, we will use the DVD file which is around 4gb and you can burn it on USB with the help of Etcher or any other tool. I am using VMware in this installation.
Most of the times we will use default options unless you know what you are doing. These options can be changed later after installation. In language will select English (US) and also the Keyboard.
The reason they are included by RedHat is explained here. (Configuring and applying scap policies during installation). If you don’t know about it, can select the first one.
Then you will have to specify installation which can be local media such as DVD or USB and can be network installation. Here we are using USB. After that, we have to select a software selection to decide what we want to install. We can install a basic server with no GUI and also can select with Gnome 3 or KDE installations.
Many other options such as Virtualization Host, File and Printer Server, and Server with GUI can be selected if you want specific installation.
Here we are using Gnome Desktop as many people don’t know Command Line Interface and are comfortable with GUI.
After that, we will go with default options and then we have to set root password and we can add users.
You can create users or can leave it default but working in root environment can be dangerous as it gives you full control but with freedom comes responsibility.

After installing the operating system, you can reboot and can login into the newly installed distro.
It looks pretty much the same as Fedora or any other Gnome desktop distro.
