Pick your free space, select New, then
choose a Primary or Logical partition. For a small server, it probably
doesn't matter too much, but remember in x86 Linux that you can have a
maximum of 4 primary + extended partitions per disk. Beyond that, you'll
need to begin adding logical partitions in your extended partitions.
Select the Write command to create the partition, then (if necessary) reboot your system.
