I can’t create a new partition

Cause: If your computer has multiple hard disks or has unallocated space on the first disk, you can create additional partitions. Having partitions works like having different hard disks, by enabling you to store data in a more organized manner. Different partitions on the same disk can use different file systems and can be used for different purposes. To create a new partition, you must have unallocated space from which to create the partition, you must be logged on as an administrator, and you must use the Disk Management utility to create the partition.
