Depending on your choice, you may get one or more screens about choosing packages
Choose whether you prefer to use the KDE or Gnome desktop environment. Both come with a full set of useful applications and tools. Tick Custom if you want to use neither or both, or if you want something other than the default software choice for these desktop environments.
Packages have been sorted into groups, to make installing what you need on your system a lot easier.
You can choose a Minumal Installation by deselecting everything in the Package Group Selection screen. Minimal Installation is intended for those with specific uses in mind for their Mageia, such as a server or a specialised workstation. You will probably use this option combined with Manual Package Selection. If you choose this installation class, then the next screen will offer you a few useful extras to install, such as documentation and X, if you wish.
