How to delete a partition?
When you delete a hard disk partition or volume (the terms partition and volume are often used interchangeably), you create empty space that you can use to create new partitions. If your hard disk is currently set up as a single partition, then you cannot delete it. You also cannot delete the system partition, boot partition, or any partition that contains the virtual memory paging file, because Windows needs this information to start correctly. Note: All data on a partition will be lost when you delete it. Be sure to back up any files that you want to save to a different location before you continue. Please follow the steps below to do this: I. Open Disk Management . II. Right-click the volume, such as a partition or logical drive that you want to delete, and then click Delete Volume . III. Click Yes to delete the partition.
