如果Windows 11启动问题阻止您启动 PC，则恢复USB可能是使其正常工作与否的区别。
继续阅读以了解如何创建Windows 11恢复USB驱动器，以及在必须使用它时必须执行的操作。以下说明也适用于旧版本的操作系统，例如Windows 10。
什么是Windows 11 恢复 USB 驱动器(Recovery USB Drive)？
与其前身一样，Windows 11容易受到启动错误的影响，从而导致其无法加载。恢复USB可让您通过访问WinRE（Windows 恢复环境）中的系统恢复选项(system recovery options in WinRE (Windows Recovery Environment))来解决这些问题。如果驱动器包含您 PC 的系统数据，如果您的故障排除尝试失败，您还可以重新安装Windows 11 。
Windows 11恢复USB驱动器不包含个人文件和应用程序。如果您希望在重新安装操作系统时恢复 PC 上的所有数据，则必须激活文件历史记录或定期进行系统映像备份(activate File History or take regular system image backups)。或者，使用专用的第三方备份软件(third-party backup software)。
如果您想继续设置恢复USB驱动器，则需要一个足够大的闪存驱动器(you need an adequately-sized flash drive)- 如果您希望它包含系统文件，则为 16-32 GB，如果不包含，则为 1 GB(GBif)。您的恢复USB驱动器也与您的计算机相关联，因此请确保在您的计算机遇到任何问题之前创建它。(before)
创建Windows 11 恢复 USB 驱动器(Recovery USB Drive)
要创建恢复USB驱动器，您必须使用名为(USB)Recovery Drive Creator的内置Windows 11实用程序。它会引导您完成该过程的每一步，并在最后自动复制所需的文件。您将丢失您计划使用的USB(USB)闪存驱动器上的所有现有数据，因此在开始之前将其上的所有内容复制到您的 PC。
注意(Note)：如果您将 PC 上的系统数据备份到恢复USB，则至少有 16 GB 存储空间的闪存驱动器就足够了。但是，某些Windows 11系统可能需要 32 GB 驱动器。您将在第五步中看到确切的尺寸。
1. 选择任务栏上的搜索(Search)按钮，在搜索框中输入Recovery Drive ，然后按(Recovery Drive )Enter。
2.在用户帐户控制(User Account Control )对话框中选择是。(Yes)
3.如果要在恢复驱动器中包含系统文件，请选中将系统文件备份到恢复驱动器(Back up system files to the recovery drive)旁边的框。然后，选择下一步(Next)。
4.等到(Wait)Recovery Drive Creator完成对前面任务的准备。
5. 在可用驱动器(Available drive(s))部分下选择您的闪存驱动器。确保(Make)您的闪存驱动器列出了可用空间。如果您连接了多个外部驱动器，请在选择时密切注意以避免不必要的数据丢失。
6. 选择创建(Create)以启动恢复驱动器创建过程。
7.等到(Wait)Recovery Drive Creator完成创建恢复驱动器。如果您将驱动器设置为包含系统数据，则该过程最多可能需要一个小时才能完成。在此期间，请(Feel)随时继续在您的 PC 上工作。
8.恢复驱动器准备就绪后，选择完成。(Finish)
9. 断开可启动USB驱动器与 PC 的连接。将其存放在安全的地方，以便在操作系统发生故障时可以快速找到它。
使用 Windows 11 恢复 USB 驱动器
如果Windows 11反复加载失败，您的计算机将自动启动到其恢复分区。与恢复驱动器相比，恢复分区提供了额外的故障排除选项，例如能够以安全模式启动 Windows 11(boot Windows 11 in Safe Mode)并在保持数据完整的同时重置操作系统(reset the operating system while keeping your data intact)。
如果恢复分区不可访问或其选项不起作用，您应该只使用恢复USB驱动器。(USB)在这种情况下，请连接USB驱动器并重新启动系统。打开 One-Time Boot Menu（在启动过程中按(Boot Menu—press) Esc或F12）并指定要从可移动媒体而不是硬盘驱动器或SSD启动。或者通过 BIOS 或 UEFI 更改引导顺序(change the boot order via the BIOS or UEFI)。
一旦您的 PC 启动到恢复驱动器，您必须选择键盘布局（例如US ）才能继续。然后，您将看到一个屏幕，其中包含从驱动器恢复(Recover from a drive )（仅当驱动器包含系统数据时可用）和对PC进行故障排除的选项。(Troubleshoot)
在从驱动器恢复之前（重新安装Windows 11），您必须选择故障排除(Troubleshoot)并使用可用的系统恢复工具来修复操作系统。以下是每个高级选项的简要功能：
- 启动修复(Startup Repair)：启动启动修复的自动序列。首先尝试此选项，如果失败，请重新启动到恢复驱动器。
- 命令提示符(Command Prompt)：执行命令行故障排除。例如，您可以运行系统文件检查器(run the System File Checker)和检查磁盘实用程序(Check Disk Utility)来解决稳定性问题和驱动器错误。
- 卸载更新(Uninstall Updates)：删除可能最终导致问题的操作系统的最新质量或功能更新。
- UEFI 固件设置(UEFI Firmware Settings)：访问UEFI（统一可扩展固件接口(Unified Extensible Firmware Interface)）并修改您 PC 的固件(modify your PC’s firmware)。
- 系统还原：如果您激活了(System Restore)系统还原(System Restore)，则将您的计算机还原到较早的启动状态并撤消最近的更改。
- 系统映像恢复：(System Image Recovery)使用(using a system image)系统映像恢复操作系统和个人数据。
如果所有修复都不起作用，请返回上一个屏幕并在主屏幕上选择从驱动器恢复以重新安装(Recover from a drive)Windows 11。
警告：(Warning: )如果此时重新安装 Windows 11，您将丢失 PC 上的所有个人数据，除非您有备份。
安全是有代价的
尽管您可能永远不需要USB恢复驱动器，但确保安全是值得的。文件(File)损坏、磁盘错误、错误的操作系统更新和其他潜在问题总是会使操作系统面临风险。
为获得最佳效果，请复制系统文件，以便在必要时快速重新安装操作系统。这样，您就不必重新下载Windows或从头开始创建安装介质。此外，请确保定期备份个人文件，以便在情况变得糟糕时恢复它们。
How to Create and Use a Windows 11 Recovery USB Drive
If Windowѕ 11 startup problems prevent you from booting your PC, a recovery USB could be the difference between getting іt working correctly or not.
Read on to learn how to create a Windows 11 recovery USB drive and what you must do if you have to use it. The instructions below also apply to older versions of the operating system, such as Windows 10.
What Is a Windows 11 Recovery USB Drive?
Like its predecessors, Windows 11 is susceptible to startup errors that can stop it from loading. A recovery USB lets you resolve them by providing you access to the system recovery options in WinRE (Windows Recovery Environment). If the drive contains your PC’s system data, you also can reinstall Windows 11 should your attempts at troubleshooting fail.
A Windows 11 recovery USB drive does not include personal files and apps. If you want the option of restoring all data on your PC in case of an operating system reinstallation, you must activate File History or take regular system image backups. Alternatively, use dedicated third-party backup software.
If you want to go ahead and set up a recovery USB drive, you need an adequately-sized flash drive—16-32 GB if you want it to include system files or 1 GBif you don’t. Your recovery USB drive is also tied to your computer, so make sure to create it before your computer runs into any issues.
Create a Windows 11 Recovery USB Drive
To create a recovery USB drive, you must use a built-in Windows 11 utility called the Recovery Drive Creator. It walks you through every step of the process and automatically copies the required files at the end. You will lose all existing data on the USB flash drive you plan to use, so copy everything on it to your PC before you begin.
Note: If you back up the system data on your PC to the recovery USB, a flash drive with at least 16 GB of storage should suffice. However, some Windows 11 systems may require a 32 GB drive. You will see the exact size in step five.
1. Select the Search button on the taskbar, type Recovery Drive in the search box, and press Enter.
2. Select Yes on the User Account Control dialog.
3. Check the box next to Back up system files to the recovery drive if you want to include system files in the recovery drive. Then, select Next.
4. Wait until the Recovery Drive Creator finishes preparing for the task ahead.
5. Select your flash drive under the Available drive(s) section. Make sure your flash drive has the available space listed. If you have multiple external drives connected, pay close attention while selecting to avoid unwanted data loss.
6. Select Create to initiate the recovery drive creation process.
7. Wait until the Recovery Drive Creator finishes creating the recovery drive. If you’re setting up the drive to include system data, the process can take up to an hour to complete. Feel free to keep working on your PC in the meantime.
8. Select Finish once the recovery drive is ready.
9. Disconnect the bootable USB drive from your PC. Store it in a safe place so that you can quickly get to it in the event of an operating system failure.
Use a Windows 11 Recovery USB Drive
If Windows 11 repeatedly fails to load, your computer will automatically boot into its recovery partition. Compared to a recovery drive, the recovery partition offers additional troubleshooting options, such as the ability to boot Windows 11 in Safe Mode and reset the operating system while keeping your data intact.
You should only use the recovery USB drive if the recovery partition is inaccessible or its options don’t work. In that case, connect the USB drive and perform a system reboot. Open the One-Time Boot Menu—press Esc or F12 during the startup process—and specify that you want to boot up from removable media instead of the hard drive or SSD. Or change the boot order via the BIOS or UEFI.
Once your PC boots into the recovery drive, you must pick a keyboard layout—e.g., U.S.—to proceed. You will then come across a screen with options to Recover from a drive (available only if the drive contains your system data) and Troubleshoot your PC.
Before recovering from the drive (which reinstalls Windows 11), you must select Troubleshoot and use the available system recovery tools to fix the operating system. Here’s what each advanced option does in brief:
- Startup Repair: Initiate an automatic sequence of startup repairs. Try this option first and boot back into the recovery drive if it fails.
- Command Prompt: Perform command-line troubleshooting. For example, you can run the System File Checker and Check Disk Utility to resolve stability issues and drive errors.
- Uninstall Updates: Remove recent quality or feature updates to the operating system that could’ve ended up causing issues.
- UEFI Firmware Settings: Access the UEFI (Unified Extensible Firmware Interface) and modify your PC’s firmware.
- System Restore: Restore your computer to an earlier start and undo recent changes if you have System Restore active.
- System Image Recovery: Restore the operating system and personal data using a system image.
If none of the fixes work, head back to the previous screen and select Recover from a drive on the main screen to reinstall Windows 11.
Warning: If you reinstall Windows 11 at this point, you will lose all personal data on your PC unless you have a backup.
It Pays to Be Safe
Although you may never need your USB recovery drive, it pays to be safe. File corruption, disk errors, buggy operating system updates, and other potential issues can always put the operating system at risk.
For best results, copy your system files so that you can quickly reinstall the operating system if necessary. That way, you avoid having to re-download Windows or create installation media from scratch. Also, make sure to back up personal files regularly so that you get to restore them if things turn ugly.
