1. Select the unallocated space on a hard drive, and then click Create from the Feature List. To create a partition/dynamic volume, before proceeding to the next step, you need to select a partition/volume type and add disk(s) to this volume.

2. In the opened window, enter a partition label to easily identify the partition later, and assign a vacant drive letter from the drop-down list to associate with this partition. 

3. Select the desired File System, Cluster Size, and choose to create this partition as Primary or Logical. Generally, Primary should be selected if the partition created is used for the operating system. Otherwise, you can keep this partition logical.  
4. Drag-and-drop the border of the light blue bar or fill in the dialogs to define the partition size and position.

5. Click OK when ready. All the introduced changes to the disk layout will be pended until applied in Pending Operation List.
