How to create or partition a hard disk.

    WARNING: There is a risk of data loss. Deleting an existing partition to create a new partition may cause existing programs not to work properly and will delete all data on that partition.

    5. In the New Partition Wizard window, click the Next button.
    6. Under Select Partition Type, click to select the desired partition type.

      IMPORTANT: Always select Primary partition if this is the first partition on an additional hard drive.

      NOTE: If Extended partition is selected, follow the instructions to complete the wizard, then add a new logical drive.
