How to fix
“Windows cannot be installed on Dynamic Disk” error
on Windows

Hello. I tried to install Windows but I received the "Windows cannot be installed on Dynamic Disk" error. Is there a way to fix this?

When attempting to install the Windows operating system on their computer, some PC users may encounter the "Windows cannot be installed on Dynamic Disk" error. When this error occurs, the full error message usually reads: "Windows cannot be installed to this hard disk space. The partition contains one or more dynamic volumes that are not supported for installation."

This error can have serious consequences for users because it prevents them from installing Windows on the desired hard disk space. In Windows, dynamic disks are a type of disk configuration that provides advanced features such as software-based RAID,[ref en-1] spanning, and mirroring. These dynamic volumes, however, are incompatible with the Windows installation process.

The error message indicates that the selected hard disk contains one or more dynamic volumes, preventing Windows installation. This can be aggravating for users who are attempting to install a new version of Windows or perform a clean install on their system.

Users have several options for dealing with this problem. Because the Windows installation process only supports installations on basic disks, one option is to convert the dynamic disk back to a basic disk. Converting the disk back to basic will delete any dynamic volumes and allow for a clean Windows installation.

Another option is to backup any important data on the dynamic disk, then delete all volumes and recreate the disk as a basic disk during the Windows installation process. This entails erasing the disk's existing volumes and starting over with a basic disk configuration compatible with Windows installation.

In this guide, you will find 2 steps that should help you fix "Windows cannot be installed on Dynamic Disk" error. You may also try to use a maintenance tool like [d1] that can fix most system errors, BSODs,[ref en-2] corrupted files, and registry[ref en-3] issues if you experience any other OS issues.

• Choose Convert to Basic Disk from the context menu.

Method 2. Run DISKPART

• Open the Command Prompt as an Administrator.
•  Run the following commands and press Enter after each one:

list disk

select disk n (“n” refers to the disk number of the dynamic that you want to convert)

list volume select volume m (“m” is the number of the volume on the dynamic disk)

delete volume (repeat these two commands to delete all volumes)

select disk n

convert basic

• When the conversion is complete, exit the Command Prompt.
