To delete a partition or logical drive:
1. In the Disk Management window, right-click the partition or logical drive that you want to delete, and then click Delete Partition or Delete Logical Drive.
2. Click Yes when you are prompted to delete the partition or logical drive. The partition or logical drive is deleted.
Important
• When you delete a partition or a logical drive, all the data on that partition or logical drive, and the partition or the logical drive, are deleted.
• You cannot delete the system partition, boot partition, or a partition that contains the active paging (swap) file.
• You cannot delete an extended partition unless the extended partition is empty. All logical drives in the extended partition must be deleted before you can delete the extended partition.
