\marginnote{Many people installing Ubuntu for the first time currently use another operating system on their computer, such as Windows \acronym{XP}, Windows Vista, Windows 7, or Mac \acronym{OS X}. Ubuntu provides you with the option of either \emph{replacing} your existing operating system altogether, or installing Ubuntu alongside your existing system. The latter is called \emph{dual-booting}. Whenever you turn on or restart your computer, you will be given the option to select which operating system you want to use for that session.} Use this option if you want to erase your entire disk. This will delete any existing operating systems that are installed on that disk, such as Windows \acronym{XP}, and install Ubuntu in its place. This option is also useful if you have an empty hard drive, as Ubuntu will automatically create the necessary partitions for you.
