格式化分区时，如果您看到消息Windows 无法格式化此磁盘上的系统分区，^{(Windows cannot format the system partition on this disk)}那么这篇文章将对您有所帮助。如果您选择在Windows 10和其他一些旧版本上格式化系统盘^{(format the system disk)}，虽然这是一个罕见的错误，但您可以解决该问题。

许多人使用双启动工具在 Windows 10/8/7 旁边安装辅助操作系统。假设您之前已经这样做了，但现在您没有使用其中一种操作系统。

要 释放一些存储空间，您需要删除包含辅助操作系统文件的分区。人们使用的最简单的方法是磁盘管理面板^{(use is the Disk Management panel)}。但是，它可能会向您显示上述错误消息。如果它发生在你身上，你有两个选择——

• 您必须通过命令提示符使用^{(Command Prompt)}Diskpart实用程序来删除卷或分区。
• 您可以使用PowerShell来执行相同的操作。

我们在本文中展示了这两种方法。

Windows 无法格式化此磁盘上的系统分区

要解决此磁盘问题，请按照下列步骤操作 -

1. 使用 Diskpart^{(Use Diskpart)}删除分区
2. 使用 PowerShell^{(Use PowerShell)}删除分区

要了解有关这些步骤的更多信息，请继续阅读。

1]使用Diskpart^{(Use Diskpart)}删除分区

Diskpart 是一个命令行实用程序，允许用户管理连接到他们计算机的硬盘驱动器。要使用此工具删除分区，请按照下列步骤操作 -

在任务栏^(Taskbar)搜索框中搜索 cmd，找到结果，然后选择以管理员^(cmd) 身份运行 ^{( Run as administrator )}选项。单击 UAC 提示符中的 Yes 按钮以 打开提升的命令提示符窗口^{(open the elevated Command Prompt window)}。打开后，依次输入以下命令——

diskpart

list volume

现在您可以找到包含所有卷的列表。

最好的是它显示了所有类型的卷，包括 Windows 在安装操作系统时创建的卷。从列表中，您必须找出所需卷的编号并输入此命令-

select volume [number]

不要忘记将 [number] 替换为原始卷号。接下来，输入此命令-

delete volume

按下 Enter 按钮后，需要一些时间才能 删除音量^{(delete the volume)}。

阅读^(Read)：Windows 无法格式化此驱动器。退出正在使用此驱动器的任何磁盘实用程序或其他程序。

2]使用PowerShell^{(Use PowerShell)}删除分区

使用PowerShell删除分区的时间相对较少，但可能并非一直如此。但是，如果您不想运行 diskpart，您仍然可以尝试，这需要一段合理的时间。

首先，按 Win+X 并从菜单中选择 Windows PowerShell (Admin) 选项。它 会打开一个提升的 Windows PowerShell^{(opens an elevated Windows PowerShell)} 窗口。之后，输入此命令-

Get-Volume

现在您可以在屏幕上看到带有驱动器号的所有分区。记下各自的DriveLetter，然后输入此命令-

Remove-Partition –[DriveLetter]

不要忘记将 [DriveLetter] 替换为原始驱动器号。

之后，它会要求确认，您必须在其中输入 Y。

就这样！现在你有一个分配的空间。

Fix Windows cannot format the system partition on this disk

While formatting a partition, if you see a message Windows cannot format the system partition on this disk then this post will help you. Although it is a rare error that appears if you choose to format the system disk on Windows 10 and some other older versions, you can troubleshoot the issue.

Many people use a dual boot facility to install a secondary operating system alongside Windows 10/8/7. Let’s say you have done that earlier, but now you are not using one of the operating systems.

To free up some storage, you want to delete the partition containing the secondary OS files. The easiest method people use is the Disk Management panel. However, it might show you the error message as mentioned above. If it is happening with you, you have two options –

• You have to use the Diskpart utility via Command Prompt to remove the volume or partition.
• You can use PowerShell to do the same.

We have shown both methods in this article.

Windows cannot format the system partition on this disk

To fix this disk issue, follow these steps-

1. Use Diskpart to delete the partition
2. Use PowerShell to delete the partition

To learn more about these steps, keep reading.

1] Use Diskpart to delete the partition

Diskpart is a command-line utility, allows users to manage hard drives attached to their computer. To use this tool to delete the partition, follow these steps-

Search for cmd in the Taskbar search box, find the result, and select the Run as administrator option. Click the Yes button in the UAC prompt to open the elevated Command Prompt window. After opening it, enter the following commands one after one-

diskpart

list volume

Now you can find a list containing all the volumes.

The best thing is that it shows all types of volumes, including the one, which Windows creates while installing the OS. From the list, you have to find out the number of the desired volume and enter this command-

select volume [number]

Don’t forget to replace the [number] with the original volume number. Next, enter this command-

delete volume

After pressing the Enter button, it will take some time to delete the volume.

2] Use PowerShell to delete the partition

Using the PowerShell to delete a partition is comparatively less time-consuming, but it may not all the time. However, you can still try if you do not want to run the diskpart, which takes a reasonable time.

First, press Win+X and select the Windows PowerShell (Admin) option from the menu. It opens an elevated Windows PowerShell window. Following that, enter this command-

Get-Volume

Now you can see all the partitions on your screen with a drive letter. Note down the respective DriveLetter, and enter this command-

Remove-Partition –[DriveLetter]

Don’t forget to replace [DriveLetter] with the original drive letter.

Following that, it asks for confirmation, where you have to enter Y.

That’s all! Now you have an allocated space.
