Setting up /home on a separate partition

Hi,

Newbie with Linux after several crashes, I made backup and reinstalled PureOs several times.
Getting bored of this, I’m wondering how to make correctly 2 partitions on my SSD drive :

  • one for PureOs only,
  • one for my personal data, so every time I can keep my datas safe even when PureOs crashes.

I found the Disk Utility that comes with PureOs (gnome-disk-utility 3.26.2; UDisks 2.7.5)
but I don’t want to make it wrongly, can you provide any help please on this ?
