Why Can’t Install Windows 7 on Dynamic Disk

From Microsoft, you know dynamic disks are only supported for Windows 7 Enterprise/Professional/Ultimate, and Windows 7 Home Basic/Premium and Starter are not supported. Therefore, you cannot install these editions of Windows 7 on dynamic disks.

Actually, all home editions of Windows as well as Windows OS released before Windows 2000, including MS-DOS, Windows 95, Windows 98, Windows Me, and Windows NT, do not support dynamic disk.

Moreover, you can make a fresh Windows installation on a dynamic volume only if this volume was converted from a basic partition which retains an entry in the partition table. Simple volumes converted from basic partitions do not have an entry in the partition table unless they were system or boot partitions prior to conversion.

That is to say, Windows 7 can only be installed on the current system or boot volumes of the dynamic disk to ensure data security. As a result, the error Windows cannot be installed on dynamic disk often appears when you are making dual boot. At this time, the best way is to convert the dynamic disk to basic disk.
