How do I partition my hard drive when installing Tumbleweed?
I want to use the entire disk and cannot figure out how to execute this task.

Please advise.

Should be an option in the installer to use the whole disk. Or you can go to expert mode and make the setup as you wish.

I usually use GParted and set my partitions up before installing.

Not necessary, of course, you can use the Advanced Edit in the installer’s partitioner at the first screen when you see the proposal.

I personally would combine both options. First choose the “Use whole disk” option to get a nive starting point and then fine tune to my wishes with the expert partitioner.
