Simple Volume VS Primary Partition

The simple volume is dynamic storage which functions as a primary partition in Windows NT 4.0 and its older versions, can only be created on a dynamic disk.

The primary partition is a partition which can be used to boot an Operating System, can only be created on a basic disk with MBR or GPT partition table under all Windows systems.

Hence, simple volumes are based on dynamic disk while primary partitions are based on basic disk. To convert simple volume to primary partition, it equals to a switch from dynamic disk to basic disk.

That is to say, as long as you choose Windows Disk Management to convert to basic disk, you must create a hard drive backup if data is concerned.

It's not available to Convert dynamic disk to basic in Windows Disk Management as shown below.
