You can only expand a partition into contiguous, following, free space. In
partition 1 or you can create additional partitions in the free space.
After you partition all of the free space, you can expand the size of a partition only by deleting a partition
that follows (has a higher number than) the one you want to expand. In
partition 3 and then expand partition 2 to use some or all of partition 3's space.

space. You can also delete one or more partitions and expand a partition into the space.
