If you are using Disk Druid to create partitions, but cannot move to the next screen, you probably have not created all the partitions necessary for Disk Druid's dependencies to be satisfied.
You must have the following partitions as a bare minimum:
A / (root) partition
A <swap> partition of type swap
Note
When defining a partition's type as swap, do not assign it a mount point. Disk Druid automatically assigns the mount point for you.
