How to edit partitions in linux? It is necessary to transfer the place from /home to the root partition with the system. Since all programs are installed on it, and the place is almost over.
I tried it through the GParted partition editor, but when editing it, it does not allow me to reduce the space in the desired partition (home), in order to then transfer it to the root. You just enter how much space you want to leave, apply, and it returns the number as it was.
There is no option to boot via livesd.

Answer 1

are you using lvm or not? This will depend on the further solution of the problem.

Answer 2

The key after the name of the section where home lies draws, right? So while home is mounted, GParted will not allow it to be resized. And while the root partition with the system mounted by GParted will also not allow it to be resized. So just boot from livecd. Well, or from the installation disk in rescue mode so that none of the partitions being changed is mounted and there is already shamanism.

Answer 3
