When I was basically new to Linux (and I still quite am), I got a nice computer from my university, featuring a SSD (250 Gb) and a 2Tb hard disk.
I decided to use only Ubuntu, but I made the installation being distracted and I did it on the 2Tb hard disk, while I wanted it on the SSD. So now I have two partitions, one on the SSD and the other one on this 2Tb hard disk.
I need to free the 2Tb hard disk; I tried with GParted, but I don't get how to use it, plus it seems like this partition is locked.
How do I get rid of this useless partition? Do I just need to delete the linux-swap in order to be able to use the hard disk?
here what I see in Gparted
