Dynamic disk volumes can be divided into simple volume, spanned volume, striped volume, mirrored volume and RAID-5 volume. The simple volume can be created on a single dynamic disk as with partition of Basic Disk, but its space can be inconsecutive. Many people may make the system partition becomes mirrored volume to another disk, but have to break the mirrored volume to be simple volume because of some other needs. The simple volume exists on a dynamic disk but if we can convert it to the primary partition?

Once, you could have converted or changed basic disk to dynamic disk, after doing so, all partitions on basic disk will become simple volume and not primary partition though your windows is working correctly, but you cannot create a primary partition or logical partition on the dynamic disk, so you could need a way to convert simple volume to primary partition.

Windows built-in Disk Manager provides the feature of reverting dynamic disk to basic disk, but it requires you to delete all volumes on the dynamic disk, otherwise, the "Convert to basic disk" is grayed out as following.
