Dynamic disk and basic disk are two kinds of store type. Both of them support MBR and GPT partition styles. Compared with basic disk, dynamic disk supports more types of volumes, including simple volume, spanned volume, striped volume, mirrored volumes, and RAID-5 volume. If you have convert disks to dynamic in Windows 10, it means that you can complete some operations that are not allowed on basic disks.
How to convert Basic Disk to Dynamic Disk in Windows 10
This article describes the steps to convert a basic disk to a dynamic disk in Windows 7.NOTE: When you convert a disk to dynamic storage, Windows 7 can read it, but the other operating systems may not. This process is not reversible. To change the format of a disk and return to basics, you should create partitions on the drive again. You should also take into account that some portable computers do not support dynamic disks. It is highly recommended that you perform a full backup of the hard disk before making any changes to your partitions, see the article Backing up data on a Windows-based computer for help with procedures.

When necessary, you might need to convert basic disk to dynamic disk for further use. However, do you know how to convert to dynamic disk without data loss? Now, you can read this post to get two available ways.
A basic disk uses a partition table to manage all basic partitions on the hard disk, and it is used by the Microsoft MS-DOS operating system and all Windows operating system versions. And a dynamic disk is supported in Windows 2000 and the later operating systems.
Dynamic disks and dynamic volumes rely on the Logical Disk Manager (LDM), Virtual Disk Service (VDS) and their associated features. And it is these features that enable you to convert basic disk to dynamic disk without data loss by using the Windows snap-in Disk Management and diskpart command line.
Both these two warnings tell you that you are unable to start installed operating systems from any volume on this disk except the current boot one. So the basic disk is not recommended to be converted to dynamic disk if you are planning to run dual or multi Windows well.
Both Disk Management and Diskpart can convert basic disk to dynamic disk without data loss. However, the reverse conversion will cause data loss if you are still using these two snap-in dynamic disk converters because you have to delete all volumes on the target dynamic disk first.
For Windows XP and the earlier versions, you still need to select the target dynamic disk and choose Convert to Basic Disk manually. While, in the later Windows versions, the dynamic disk will be converted to basic disk automatically once you delete all volumes on it.
MiniTool Partition Wizard, a professional partition manager, is designed to partition and repartition hard disks, as well make some powerful conversions including Convert Dynamic Disk to Basic Disk, and more.
The inter-conversions between basic disk and dynamic disk can have no data loss as long as you select a right tool. All in all, you can convert basic disk to dynamic disk without data loss with Windows snap-in Disk Management or diskpart. And then you are able to convert dynamic disk to basic disk with all data are kept well by using MiniTool Partition Wizard if it is necessary.
This topic describes how to delete everything on a dynamic disk and then convert it back to a basic disk. Dynamic disks have been deprecated from Windows and we don't recommend using them anymore. Instead, we recommend using basic disks or using the newer Storage Spaces technology when you want to pool disks together into larger volumes. If you want to mirror the volume from which Windows boots, you might want to use a hardware RAID controller, such as the one included on many motherboards.
For the purposes of this topic, the term volume is used to refer to the concept of a disk partition formatted with a valid file system, most commonly NTFS, that is used by the Windows operating system to store files. A volume has a Win32 path name, can be enumerated by the FindFirstVolume and FindNextVolume functions, and usually has a drive letter assigned to it, such as C:. For more information about volumes and file systems, see File Systems.
Basic disks are the storage types most often used with Windows. The term basic disk refers to a disk that contains partitions, such as primary partitions and logical drives, and these in turn are usually formatted with a file system to become a volume for file storage. Basic disks provide a simple storage solution that can accommodate a useful array of changing storage requirement scenarios. Basic disks also support clustered disks, Institute of Electrical and Electronics Engineers (IEEE) 1394 disks, and universal serial bus (USB) removable drives. For backward compatibility, basic disks usually use the same Master Boot Record (MBR) partition style as the disks used by the Microsoft MS-DOS operating system and all versions of Windows but can also support GUID Partition Table (GPT) partitions on systems that support it. For more information about MBR and GPT partition styles, see the Partition Styles section.
You can add more space to existing primary partitions and logical drives by extending them into adjacent, contiguous unallocated space on the same disk. To extend a basic volume, it must be formatted with the NTFS file system. You can extend a logical drive within contiguous free space in the extended partition that contains it. If you extend a logical drive beyond the free space available in the extended partition, the extended partition grows to contain the logical drive as long as the extended partition is followed by contiguous unallocated space. For more information, see How Basic Disks and Volumes Work.
For all usages except mirror boot volumes (using a mirror volume to host the operating system), dynamic disks are deprecated. For data that requires resiliency against drive failure, use Storage Spaces, a resilient storage virtualization solution. For more info, see Storage Spaces Overview.
Dynamic disks provide features that basic disks do not, such as the ability to create volumes that span multiple disks (spanned and striped volumes) and the ability to create fault-tolerant volumes (mirrored and RAID-5 volumes). Like basic disks, dynamic disks can use the MBR or GPT partition styles on systems that support both. All volumes on dynamic disks are known as dynamic volumes. Dynamic disks offer greater flexibility for volume management because they use a database to track information about dynamic volumes on the disk and about other dynamic disks in the computer. Because each dynamic disk in a computer stores a replica of the dynamic disk database, for example, a corrupted dynamic disk database can repair one dynamic disk by using the database on another dynamic disk. The location of the database is determined by the partition style of the disk. On MBR partitions, the database is contained in the last 1 megabyte (MB) of the disk. On GPT partitions, the database is contained in a 1-MB reserved (hidden) partition.
Dynamic disks are a separate form of volume management that allows volumes to have noncontiguous extents on one or more physical disks. Dynamic disks and volumes rely on the Logical Disk Manager (LDM) and Virtual Disk Service (VDS) and their associated features. These features enable you to perform tasks such as converting basic disks into dynamic disks, and creating fault-tolerant volumes. To encourage the use of dynamic disks, multi-partition volume support was removed from basic disks, and is now exclusively supported on dynamic disks.
Another difference between basic and dynamic disks is that dynamic disk volumes can be composed of a set of noncontiguous extents on one or multiple physical disks. By contrast, a volume on a basic disk consists of one set of contiguous extents on a single disk. Because of the location and size of the disk space needed by the LDM database, Windows cannot convert a basic disk to a dynamic disk unless there is at least 1 MB of unused space on the disk.
Regardless of whether the dynamic disks on a system use the MBR or GPT partition style, you can create up to 2,000 dynamic volumes on a system, although the recommended number of dynamic volumes is 32 or less. For details and other considerations about using dynamic disks and volumes, see Dynamic disks and volumes.
Unless specified otherwise, Windows initially partitions a drive as a basic disk by default. You must explicitly convert a basic disk to a dynamic disk. However, there are disk space considerations that must be accounted for before you attempt to do this.
Partition styles, also sometimes called partition schemes, is a term that refers to the particular underlying structure of the disk layout and how the partitioning is actually arranged, what the capabilities are, and also what the limitations are. To boot Windows, the BIOS implementations in x86-based and x64-based computers require a basic disk that must contain at least one master boot record (MBR) partition marked as active where information about the Windows operating system (but not necessarily the entire operating system installation) and where information about the partitions on the disk are stored. This information is placed in separate places, and these two places may be located in separate partitions or in a single partition. All other physical disk storage can be set up as various combinations of the two available partition styles, described in the following sections. For more information about other system types, see the TechNet topic on partition styles.
Dynamic disks follow slightly different usage scenarios, as previously outlined, and the way they utilize the two partition styles is affected by that usage. Because dynamic disks are not generally used to contain system boot volumes, this discussion is simplified to exclude special-case scenarios. For more detailed information about partition data block layouts, and basic or dynamic disk usage scenarios related to partition styles, see How Basic Disks and Volumes Work and How Dynamic Disks and Volumes Work. 2ff7e9595c
