How can I move/resize system partition to the left?

When I installed EndeavourOS I made a new partition on my Windows drive. Now I deleted Windows and I’m left with this big partition sitting in the middle between the boot and system partitions and it makes me feel… uncomfortable.

Is there a way to move or resize the system partition or is my only option reinstalling it?

You have to move it to the left, then you can expand it to the right.

Be aware that there is some risk in partition changes. Be sure you have your data backed up first.

how can I move it? hehe i don’t think i’ve ever done this before so i’m not really sure of how it’s done

any method or software you recomend?

Well both KDE and Gnome have disk partitioning software. I have used both, but couldn’t recommend either (as it seem corrupting the partition happens sometimes with either..the warning is not being alarmist).
And, I feel that the software isn’t so much buggy as moving partitions wholesale verges on witchcraft.
