As Kubuntu is part of the Ubuntu family you can install it on its own or alongside other operating systems, including Windows 8 with EFI enabled.
I decided to install Kubuntu 13.10 alongside Ubuntu 13.10 and Windows 8 on the same machine which is a Dell Inspiron 15.
The Kubuntu installer is probably the best I have ever seen for any operating system. The layout is crisp, completely intuitive and easy to follow.
New users might stumble when installing alongside Windows 8 but I have written a guide showing how to install Ubuntu alongside Windows 8 and most of this works for Kubuntu 13.10 as well. (Some of the screens may be different but the logic is the same).
