^{(Running Microsoft Windows alongside macOS)}借助Boot Camp、VirtualBox和Parallels等工具，在Mac上^(Mac)运行 Microsoft Windows 和 macOS变得异常简单。然而，鉴于Mac^(Mac)设备的存储空间通常有限，从长远来看，维持多操作系统设置并不完全可持续。

如果您希望释放空间、整理系统或从Windows^(Windows)过渡，本指南将引导您完成从任何MacBook、i Mac或Mac mini 安全卸载Windows的步骤。

在Boot Camp 安装^{(Boot Camp Installation)}中卸载Windows

Boot Camp是 Apple在基于 Intel 的 Mac 上获取 Windows^{(get Windows on Intel-based Macs)}的本机解决方案。它处理所有事情，从在硬盘驱动器或SSD上创建单独的分区、下载所需的硬件驱动程序，到设置Windows安装。

如果您的Mac上有Boot Camp提供的Windows，您可以卸载操作系统并通过Boot Camp本身将^{(Boot Camp)}Windows分区与主 macOS 卷重新集成。

备份您的 Windows 数据

Time Machine不会备份与Windows相关的数据，因此在开始之前，请创建数据副本，以避免永久失去对重要文件和文件夹的访问权限。

为此，请在打开Mac时按住^(Mac)Option键，然后选择Boot Camp以启动至Windows。然后，打开文件资源管理器^{(File Explorer)}，转到BOOTCAMP (C:) > 用户，然后将您的用户帐户文件夹移动到外部驱动器或云存储服务。

通过BCA卸载Boot Camp 分区^{(Boot Camp Partition)}

备份数据后，可以使用macOS 中的Boot Camp Assistant ( BCA ) 实用程序来删除^(BCA)Windows。启动时进入^(Enter)启动选择界面，选择Macintosh HD启动进入macOS，然后：

1. 打开Finder，导航至Applications > Utilities，然后打开Boot Camp Assistant。

1. ^{(Select Continue)}在Boot Camp Assistant^{(Boot Camp Assistant)}欢迎屏幕 上选择继续。

1. 选择标记为“恢复”的按钮。

注意：在macOS Catalina及更早版本的^(Catalina)Boot Camp Assistant中，您将看到一个附加屏幕，您必须在其中选择“删除 Windows 7^{(Remove Windows 7)}或更高版本”或“删除^(Remove)Windows 10 或更高版本”才能继续。

1. 在身份验证弹出窗口中 输入您的Mac管理员密码，然后选择“确定”。^(Mac)

1. 等待^(Wait)Boot Camp Assistant擦除Windows并将内部磁盘恢复为单个 macOS 分区。该过程可能需要一段时间，因此请耐心等待。

1. 选择“退出”^{(Select Quit)}以退出Boot Camp 助手^{(Boot Camp Assistant)}。

1. 重新启动^(Reboot)macOS — 打开Apple菜单并选择重新启动 — 以^{(Restart—to)}完成Windows删除过程。

^{(Remove Boot Camp Partition)}通过磁盘工具^{(Disk Utility)}删除 Boot Camp 分区

如果您在尝试通过Boot Camp Assistant删除^{(Boot Camp Assistant)}Windows 操作系统^{(Windows OS)}时遇到“您的^(Your)磁盘无法恢复到单个分区”错误消息，您可以依靠下面基于磁盘实用程序^{(Disk Utility)}的方法。只是：

1. 调用 Spotlight 搜索^{(Invoke Spotlight Search)}（按Command + Spacebar）并启动“磁盘工具”^{(Disk Utility)}。

1. 选择“磁盘工具”^{(Disk Utility)}窗口顶部的“分区”^(Partition)按钮。

1. ^{(Highlight BOOTCAMP)}在饼图视图中突出显示 BOOTCAMP并选择减号^(Minus)按钮。

1. 选择应用。

1. 选择分区。

1. 保持^(Stay)不变，因为磁盘工具^{(Disk Utility)}会擦除Windows磁盘并将其与主 macOS 卷合并。

注意：如果您在删除Windows^(Windows)时仍然遇到问题，请在 Mac 恢复模式下使用“磁盘工具”^{(using Disk Utility in Mac Recovery Mode)}重复上述步骤。

从虚拟化应用程序^{(Virtualization Apps)}中删除Windows

与 Boot Camp 相比，VirtualBox 等虚拟化软件^{(virtualization software like VirtualBox)}使在Mac上使用Windows更加方便，因为您无需从 macOS 启动即可与操作系统交互。付费^(Paid)工具（例如Parallels Desktop）甚至^{(Parallels Desktop—even)}支持在Apple Silicon Mac^{(Apple Silicon Macs)}上运行ARM 版本的 Windows^{(ARM versions of Windows)}。

删除Windows虚拟机 (VM) 同样方便。没有单独的分区需要处理；您所要做的就是指示虚拟化程序删除与VM关联的虚拟磁盘文件。作为示例，以下是如何在VirtualBox和Parallels中卸载^(Parallels)Windows VM。

备份重要^{(Backup Important)}文件：在删除任何内容之前，请将所有重要数据从Windows虚拟机复制到Mac或外部存储设备。

从 VirtualBox 中删除 Windows 安装^{(Remove Windows Installation From VirtualBox)}

1. 打开Oracle VM VirtualBox Manager并在侧边栏上突出显示要删除的Windows安装。^(Windows)如果虚拟机处于活动状态，请先将其关闭。

1. 选择顶部菜单上的“机器” ，然后选择^(Machine)“删除”^(Remove)。

1. 选择删除^(Delete)所有文件按钮。

1. 转到 Mac 的废纸篓^(Trash)并将其清空，以完全删除虚拟机并释放内部磁盘上的空间。

如果您想从Mac中删除^(Mac)VirtualBox安装，请使用与 VirtualBox 安装程序捆绑在一起的VirtualBox卸载工具^{(VirtualBox Uninstall Tool)}。请查看我们的VirtualBox for Mac 删除指南^{(VirtualBox for Mac removal guide)}以获取详细说明。

从 Parallels Desktop 中删除 Windows 安装^{(Remove Windows Installation From Parallels Desktop)}

1. 打开Parallels Desktop，选择Parallels Desktop状态图标，然后选择控制中心^{(Control Center)}。

1. 关闭^(Shut)Windows虚拟机（如果处于活动状态），然后在菜单栏上 选择File > Remove [虚拟机名称]”。^(Windows)

1. 选择移至垃圾箱。

要在Mac上卸载^(Mac)Parallels，请退出所有正在运行的虚拟机，访问“应用程序”文件夹，然后将^{(Applications)}Parallels拖放到“废纸篓”^(Trash)中。您可以通过Safari或任何其他网络浏览器 登录您的Parallels 帐户^{(Parallels account)}来管理您的Parallels订阅。^(Parallels)

您现在是一名全职 Mac 用户

您现在知道如何从Mac计算机上卸载完整的^(Mac)Windows安装或虚拟机。虽然步骤很简单，但请始终优先考虑备份数据。如果您只是对Windows进行故障排除，请在准备好后重新安装操作系统。

顺便问一下，您是否知道无需安装 Windows 也可以在 Mac 上使用 Windows 应用程序^{(use Windows apps on the Mac without installing Windows)}？

How to Uninstall Windows From Your Mac

Running Microsoft Windows alongside macOS on a Mac is ridiculously easy, thanks to tools like Boot Camp, VirtualBox, and Parallels. However, given the often-limited storage of Mac devices, maintaining a multi-OS setup is not exactly sustainable in the long run.

If you’re looking to free up space, declutter your system, or transition away from Windows, this guide walks you through the steps to safely uninstall Windows from any MacBook, iMac, or Mac mini.

Uninstall Windows in a Boot Camp Installation

Boot Camp is Apple’s native solution to get Windows on Intel-based Macs. It handles everything, from creating a separate partition on the hard drive or SSD, downloading the required hardware drivers, to setting up the Windows installation.

If you have Windows on your Mac courtesy of Boot Camp, you can uninstall the operating system and reintegrate the Windows partition with the main macOS volume through Boot Camp itself.

Back-Up Your Windows Data

Time Machine does not back up data related to Windows, so before you begin, create a copy of your data to avoid permanently losing access to important files and folders.

To do that, hold the Option key as you turn on your Mac and choose Boot Camp to boot into Windows. Then, open File Explorer, go to BOOTCAMP (C:) > Users, and move your user account folder to an external drive or cloud storage service.

Uninstall Boot Camp Partition via BCA

After backing up your data, it’s time to use the Boot Camp Assistant (BCA) utility in macOS to remove Windows. Enter the boot selection screen at startup, select Macintosh HD to boot into macOS, and then:

1. Open Finder, navigate to Applications > Utilities, and open Boot Camp Assistant.

1. Select Continue on the Boot Camp Assistant welcome screen.

1. Select the button labeled Restore.

Note: In Boot Camp Assistant for macOS Catalina and older, you’ll be presented with an additional screen where you must choose Remove Windows 7 or later version or Remove Windows 10 or later version to proceed.

1. Enter your Mac administrator password into the authentication pop-up and select OK.

1. Wait until Boot Camp Assistant erases Windows and restores the internal disk as a single macOS partition. The procedure can take a while, so be patient.

1. Select Quit to exit the Boot Camp Assistant.

1. Reboot macOS—open the Apple menu and select Restart—to finalize the Windows removal process.

Remove Boot Camp Partition via Disk Utility

If you encounter a “Your disk could not be restored to a single partition” error message while attempting to remove the Windows OS via Boot Camp Assistant, you can rely on the Disk Utility-based approach below. Just:

1. Invoke Spotlight Search (press Command + Spacebar) and launch Disk Utility.

1. Select the Partition button on the top of the Disk Utility window.

1. Highlight BOOTCAMP within the pie chart view and select the Minus button.

1. Select Apply.

1. Select Partition.

1. Stay put as Disk Utility wipes and merges the Windows disk with the primary macOS volume.

Note: If you continue to run into issues removing Windows, repeat the steps above using Disk Utility in Mac Recovery Mode.

Remove Windows From Virtualization Apps

Compared to Boot Camp, virtualization software like VirtualBox makes using Windows on a Mac more convenient since you can interact with the operating system without having to boot out of macOS. Paid tools—such as Parallels Desktop—even support running ARM versions of Windows on Apple Silicon Macs.

Removing a Windows virtual machine (VM) is just as convenient. There are no separate partitions to deal with; all you have to do is instruct the virtualization program to delete the virtual disk files associated with the VM. As examples, here’s how uninstalling a Windows VM works in VirtualBox and Parallels.

Backup Important Files: Before you delete anything, copy any essential data from the Windows virtual machine to your Mac or an external storage device.

Remove Windows Installation From VirtualBox

1. Open the Oracle VM VirtualBox Manager and highlight the Windows installation you want to delete on the sidebar. If the virtual machine is active, power it down first.

1. Select Machine on the top menu and choose Remove.

1. Select the Delete all files button.

1. Go to your Mac’s Trash and empty it to completely remove the virtual machine and free up space on the internal disk.

If you want to remove the VirtualBox installation from your Mac, use the VirtualBox Uninstall Tool bundled with the VirtualBox installer. Check our VirtualBox for Mac removal guide for detailed instructions.

Remove Windows Installation From Parallels Desktop

1. Open Parallels Desktop, select the Parallels Desktop status icon, and choose Control Center.

1. Shut down the Windows virtual machine if active and choose File > Remove [virtual machine name] on the menu bar.

1. Select Move to Trash.

To uninstall Parallels on your Mac, quit all running virtual machines, visit the Applications folder, and drag and drop Parallels into the Trash. You can manage your Parallels subscription by signing into your Parallels account via Safari or any other web browser.

You’re Now a Full-Time Mac User

You now know what it takes to uninstall a full-fledged Windows installation or virtual machine from a Mac computer. While the steps are straightforward, always prioritize backing up your data. If you’re just troubleshooting Windows for issues, feel free to reinstall the OS when you’re ready.

By the way, did you know you can also use Windows apps on the Mac without installing Windows?
