Install PureOS with manual partitioning

This procedure will install PureOS with manual partitioning. The partition layout shown below works for any size disk, including disks larger than 2 TB.

If you are familiar with partitioning a Linux system, you can also customize the partition layout, such as to use a second SSD.
