Create a partition from unpartitioned space with these steps:

  4. To do this, right-click your main drive and select Shrink Volume.
  5. Now enter the amount that you want to shrink the hard disk by in megabytes (MB).
  6. After the Shrink is done, you will then see the region of unallocated space (shaded black). Remember, this space is not yet usable.
  7. Right-click the region of unallocated space and select New Simple Volume.
  8. This launches the New Simple Volume Wizard and this guides you through the installation process.
  9. Assign the disk a drive letter. You can choose any drive letter that is not currently in use.
  10. Select a file system for the disk. The file system is the type of format or foundation that the storage device has. If you plan on installing a Windows operating system to the partition, select the NTFS file system.
  11. Name the partition in the Volume Label text box. You can choose any name for your partition.
  12. Now click Finish to create the new partition.
