You may want to check system requirements of Ubuntu before installing to be sure.

Installation Documents can be found here:

Installing Ubuntu is very simple if you have ever done an install of a Windows or Apple OS before you won't struggle with a Ubuntu Install.

It maybe easier for you to check if a friend has a Windows XP Machine updated with SP3 to flash your eMMC before installing Ubuntu although its entirely up to your self.

Have a read into Ubuntu, do a little bit of research into the OS before installing to be sure of what you are getting.
