I would like to install Ubuntu Studio on my computer which has currently a dual boot Ubuntu_13.04/Windows_7. Surfing in the internet I saw that it is possible to upgrade Ubuntu to Ubuntu Studio. The question is: doing the update, will I lose the current Ubuntu 13.04 OS?
For example, when installing gnome-desktop on unity, you have the possibility of choosing between the two of them when booting the system.
Is it the same in this case? If I upgrade to Ubuntu Studio installing ubuntustudio-desktop, the proper packages and the proper low-latency kernel, will I still have the possibility of choosing between GNOME, Unity and Ubuntu Studio during the boot?
