I got a bit confused after installing Linux Mint again, this time on my HDD instead of the SSD. I have not deleted the old (on the SSD) yet because I am worrying that "root" and "swap" might be shared between the two. I haven't created a "home" directory on any of them so far.
Probably obvious but I'm basically unacquainted to Linux and partitioning. If this is the really the case, please tell me how I could delete any traces of the previous, and also how to add a "home" and perhaps "root" and "swap".
