Today, with the new version of Ubuntu, I have decided to install it in my laptot, but running with Windows 8, which is the OS I have installed now and that I don't want to uninstall, because I need some programs.

I have downloaded it and burned into a CD. Everything in the "installation" goes right untill I have to choose where to install it. It doesn't recognise my Windows 8 and, moreover, it sees my disk as it was all empty space (500Gb). I can't install it and I don't know what to do, so let's see if you can help, because you know a lot more than me in this topic :)

Thanks!
