Is it possible to have a dual boot of different Ubuntu versions? X K L M E U Since only 1 gig of space is recommended you should be able to have 8 possible version on a 16 gig flash drive. Cause I really hate the scroll scroll bars in the Unity version and want to see which system I Like best XFCE, KDE, Fluxbox custom(is what my friend uses), etc.
Currently I have made 3 boot up drives all one USB drive which means erasing and reinstalling every time. Cheers,,
