I wish to dual boot ubuntu (currently installed) with fedora and/or openSUSE (fedora for vanilla gnome and SUSE for a good KDE experience). I do not know much about dual booting and grub. Do I only have to put in the liveCD and install side by side? Or do I have to partition and stuff? Also, is there an easy way to remove one if I do not want it?
Please note that I do not want them on the same /home partition, I want them to have a different one each. (and also if there is a way that is mostly graphical and user friendly, it would be most appreciated)
EDIT: What if I wanted to install something like arch of mint? how would I do that?
