If you installed both GNOME and KDE, you can choose which one you would like to be your default desktops environment. Otherwise, it will only show GNOME or KDE as the desktop default.
You can also choose whether you want to boot your system into a text or graphical environment once Fermi Linux is installed. Unless you have special needs, booting into a graphical environment (similar to a Windows environment) is recommended. If you choose to boot into a text environment, you will be presented with a command prompt (similar to a DOS environment).
