From the table, it's clear that EaseUS Partition Master is the safest and easiest way to fix this error we are focusing. Then, let's see how this tool can help convert a dynamic disk to a basic one.
If you are not a pro, turn to EaseUS Partition Master Professional. This tool can help you convert dynamic to a basic disk without losing any data, while Disk Management and CMD will delete all partitions before they can convert. Install this tool and follow the instructions below to start converting.
Step 1. Install and open EaseUS Partition Master and go to Disk Converter.
Step 2. Select the disk conversion mode that suits your need:
- Convert Basic to Dynamic: change a Basic disk to Dynamic.
- Convert Dynamic to Basic: change a Dynamic disk to Basic.
Step 3. Select the target disk - Basic or Dynamic, confirm you've select the correct disk and click "Convert" to start.
0:00 - 0:18 Convert Basic to Dynamic Disk; 0:19- 0:36 Convert Dynamic to Basic Disk.
This tool allows users to convert between basic disks and dynamic disks easily. Don't miss this tool to help you convert your dynamic disks.
After changing the disk into a basic one, you can start to install Windows 7 from USB or other media sources.
Using the built-in Windows program "Disk Management," you can also convert the disk to a basic disk to resolve the Windows 7 installation failed error. But this method requires you to delete all partitions on the dynamic disk. If you have important data, please back it up in advance.
Just open this tool, right-click on the target volume, and select "Delete Volume." When you see the warning below, just click yes to continue.
After all volumes are deleted, the disk automatically becomes a basic disk. You can then install Windows 7 on that disk.

In addition, you can use the Command Prompt to perform dynamic disk conversion. This method is difficult for beginners, and it is recommended that beginners use EaseUS Partition Master.
Follow the steps to try:
- Press Windows + R and enter "diskpart" in the Run window to launch Diskpart.
- Enter "list disk": all disks can be listed.
- Enter "select disk 1": 1 represents the disk number. Please select the target disk to convert to a basic disk.
- Then enter "Detail Disk."
- Enter "select volume 0": n represents the number of the dynamic volume.
- Then, enter "delete volume."
- Finally, enter convert basic, and you will see that diskpart successfully converts the selected disk to the basic format.
If there are multiple volumes, repeat steps 5 and 6 to delete all volumes.
With the latter two methods, you'll find a limitation: Disk Management utility and diskpart commands require you to delete all volumes before converting the dynamic disk to a basic disk, which means that all data on the disk will be lost. Therefore, to avoid the loss and inconvenience caused by data loss, it is recommended to use a trustworthy third-party software - EaseUS Partition Master.
