I am currently running LM 16, Mate. Dual booting from sda, 80 gig, which also has the XP install on it. What I would like to do, would be to partition sdb, 500 gig, wich has the running 16, mate on it. So that I could add 16 Cinnamon, and 16 Xfce.
That way, I would be able to compare the different versions. This is on an old P4 machine with 2 gigs of ram, all you can put in it, so that Cinnamon may be too much for it. But, I won't know until I try.
I have the Cinnamon and Xfce downloaded and md5sum checked and burnt. But I figure better ask before I get playing with gparted and realize I don't know enough what I am doing.
I would assume that I would boot all of them from sda? Is that right? Then divide sdb into 3 or 4 partitions? I would use just /, /home for each version, I think? Use the same swap for all 3 Mints, right?
This post is in the order of, "Measure twice, cut once" thing.
