I have a triple-booted desktop computer with Ubuntu 12.04 LTS, Windows 7 and Ubuntu 13.04. I plan to permanently keep Ubuntu 12.04 and Windows 7 but I want to switch Ubuntu 13.04 to another operating system as Unity on 13.04 seems to slow my computer down and usually freezes it.
Since I can't post images in these questions, here is the image of GParted with my set up right now:
I want to remove Ubuntu 13.04 from my triple boot but am not sure if removing it right now will mess up 12.04. I know windows 7 is sda1 to sda 3, Ubuntu 12.04 is sda 5 and Ubuntu 13.04 is sda 7. Should I just delete it? Are there any problems I should worry about?
