1.2. Server and Desktop Differences
There are a few differences between the Ubuntu Server Edition and the Ubuntu Desktop Edition. It should be noted that both editions use the same apt repositories. Making it just as easy to install a server application on the Desktop Edition as it is on the Server Edition.

The differences between the two editions are the lack of an X window environment in the Server Edition, the installation process, and different Kernel options.

1.3. Backing Up
Before installing Ubuntu Server Edition you should make sure all data on the system is backed up. See Chapter 16, Backups [p. 213] for backup options.

If this is not the first time an operating system has been installed on your computer, it is likely you will need to re-partition your disk to make room for Ubuntu.
