Remove and resize partitions in NixOS

Hello,

I’m new to NixOS. I’ve used it for a month now but i used to work with Linux Mint for two years.
Now, i’m sure to use only NixOS and i want to delete my dual-boot with Mint. So i want to remove Mint partition and resize my NixOS partition. Is it possible to do it with gparted without problems ?
All my partitions are on the same SSD.
The first partition is for my games (1000 GB), the second one is NixOS (500 GB) and the last one is Mint (500 GB).

I can provide more information if you need it.

Thanx!

Yes, but then also remove the mount from your config if it’s present there, and nixos-rebuild boot.

Hi!

Thanx it works without problems!
