Hướng Dẫn Cách Xóa Phân Vùng Recovery Partition Trong Windows

The Windows Recovery Environment (WinRE) is a companion operating system installed alongside Windows 10, typically in a separate partition, that can help with troubleshooting, recovery, or booting from external truyền thông, such as a USB stichồng. WinRE is also used during the Windows update process to apply updates in specific paths or phases. (This process is sometimes referred lớn as SafeOS.)In this post, we"re going lớn walk you through the tools in WinRE, offer tips & tricks for using it effectively, and, while we"re at it, clear up comtháng misconceptions around WinRE. We’ll also show how WinRE can enable a Windows 10 device that might have sầu issues starting or applying the lakiểm tra updates, get baông xã lớn a good state.An overview of WinREWhen talking lớn IT pros, enthusiasts, và other shimatest.shop employees, I like lớn refer lớn WinRE as the “xanh screen of life.” Some agree with me out of politeness, but I believe sầu the phrase resonates with many people because, at the end of the day, WinRE is typically used to lớn fix something.WinRE is almost always located in a separate partition that immediately follows the main Windows partition. (For more details on the mặc định partition layout for UEFI-based PCs, see our partition layout documentation.)If you are familiar with Windows PE (WinPE), this may sound similar. Think of WinPE as the base OS and WinRE as the user interface with some recovery tools added.When you launch WinRE, you may see these options: Continue (exit WinRE and continue to Windows 10), Use a device (use a USB drive, network connection, or Windows recovery DVD), Troubleshoot (remix your PC or use advanced options), and Turn off your PC.

Figure 1. Initial WinRE thực đơn optionsAccessing WinREYou can access WinRE via multiple entry points:From the Start thực đơn, select Power nguồn then select and hold down the Shift key while selectingRestart.In Windows10, selectStart>Settings>Update và Security>Recovery. UnderAdvanced startup, select Restart now.By booting to recovery truyền thông media.Note: an easy way lớn create recovery media is to lớn use the Media Creation Tool or to create a recovery drive và uncheck the Back up system files lớn the recovery drive option.Ahardware recovery button (or button combination)configured by the OEM.Here are two lesser-known ways to access WinRE:Use REAgentC. From Windows 10, run a comm& prompt as an administrator, then type reagentc /boottore. Restart the device and it will load WinRE instead of Windows 10.The shutdown command also has an entry point for WinRE. Run commvà prompt as an administrator and type shutdown /r /o.Okay, so now that you’re in WinRE, what can you do?Depending on how you started WinRE, the options may differ. For example, if you boot from a USB stiông xã, the Reset this PC option does not appear. You can continue to Windows 10 or turn off your PC.If the options presented are not desired, select Continue to start Windows 10. Likewise, the Turn off your PC option will shut down the device. If you have sầu multiple operating systems installed, this would also be where you could select which OS to boot.Use a deviceThis option helps you boot from another source such as USB, DVD, or even a network connection. This can be helpful as it is simpler than some BIOS/Unified Extensible Firmware Interface (UEFI) menus & provides a consistent experience.TroubleshootWinRE has many troubleshooting tools to lớn help you get devices back to a good state quickly and easily. For more information, see Use WinRE to lớn troubleshoot common startup issues.Now, let’s explore the options available in the Troubleshoot category.Remix this PCResetting a PC reinstalls Windows 10, but lets you choose whether khổng lồ keep your files or remove sầu them before reinstalling Windows. Remix this PC is the most popular option & offers a few options. (You can also access Rephối this PC from the Settings thực đơn if you can successfully start Windows 10.) For more information on Remix this PC, see Recovery options in Windows 10. I"ll also dive deeper inlớn Remix this PC in future posts, so stay tuned!

Figure 2. The Advanced options menuStartup RepairIf Windows fails to lớn start twice, the third attempt will run Startup Repair automatically. This is also available as an option on the advanced options page of troubleshooting. Startup Repair can help fix a corrupt master boot record (MBR), partition table, or boot sector. Beginning with Windows 10, version 1809, automatic Startup Repair also removes the most recently installed update if that installation immediately preceded the startup failure.Startup SettingsAnother troubleshooting step is to change how Windows starts up. Enabling debugging or boot logging can help identify a specific issue. This is also where you can enable Safe Mode. Cheông xã out the tư vấn page on Startup Settings for more information.Commvà PromptWhile not the most approachable tool for unfamiliar users, the commvà prompt is the most powerful and dynamic tool in WinRE. It can vày everything from registry edits to lớn copying files lớn running Deployment Image Servicing và Management (DISM) commands. Next, we’ll cover a few notable examples. (lưu ý that while using Commvà Prompt in WinRE, it automatically runs with elevated administrator permissions.)Copying filesIf you need lớn copy a few files from your device before reinstalling Windows, using a USB drive sầu or network nội dung can be a quiông xã way lớn vì this using the comm& prompt within WinRE.There is also a popular Notepad triông xã that makes it easier lớn copy files. I love it & wish I could take credit as it a big timesaver for visual people lượt thích me. !ChkdskRunning chkdsk is a common first step lớn help resolve sầu issues. This process checks the tệp tin system & tệp tin system metadata of a volume for logical và physical errors. (While in WinRE, drive letters may be assigned differently than in Windows 10. You can run BCDEdit khổng lồ get the correct drive letters.)SFCSFC scans và verifies the integrity of all protected system files and replaces incorrect versions with correct versions. If this command discovers that a protected file has been overwritten, it retrieves the correct version of the file, & then replaces the incorrect file.Repair corrupt components using DISMWindows system components may become corrupt from hard drive sầu malfunctions or update issues. If you have a wired ethernet connection, you can turn on networking lớn then scan và repair corrupted nội dung using Windows Update & the /Cleanup-Image switch in DISM.From the commvà prompt, type wpeinit and Enter to turn on the networking stack then type the following command:

dism /image:c: /cleanup-image /restorehealth

Figure 3. Using DISM within the command prompt in WinRERegistry EditorYes, you can use regedit within Windows RE, but warning: this is a powerful tool that can really mess things up if not used correctly! Keep in mind the X: drive is the WinRE OS & has its own registry. C: is likely where the Windows 10 registry is.

Figure 4. Launching the Registry Editor from the commvà prompt in WinREUninstall UpdatesRemoving the lathử nghiệm updates recently installed to lớn Windows 10 can be a good troubleshooting step if you are having trouble starting your PC or if you are having trouble uninstalling something within Windows 10. Simply select Uninstall lachạy thử chất lượng update or Uninstall lademo feature update to uninstall the desired update from WinRE with just a couple of steps. Please note; however, that you should reapply the lachạy thử updates as soon as possible to help keep your devices protected and productive sầu.

Figure 5. The Uninstall Updates menuUEFI Firmware SettingsThis option makes it easy khổng lồ boot inlớn the UEFI thực đơn to change firmware settings, especially as the many different devices offered by OEMs use different keyboard or button combinations to access UEFI. For example, some use volume buttons, function keys, the delete key, or a combination therein. WinRE provides a consistent method for accessing UEFI firmware settings across all devices.System Restore và System Image RecoveryThese two options can be useful if you are using legacy system restore features or image-based recovery. The System Restore option can restore your PC to lớn a previous restore point which, for example, could unbởi the lathử nghiệm win32 application installation if you captured a restore point prior khổng lồ the installation.Recovery DriveCreating a recovery drive sầu is a built-in Windows ability that can easily create a USB drive sầu with WinRE. Optionally, it can also “back up system files khổng lồ the recovery drive sầu,” a process that takes a while but will fully reinstall Windows onto lớn that same system even if the hard drive sầu is blank. This is often referred to lớn as Bare Metal Recovery (BMR). When starting your system from a Recovery Drive, you will notice that is uses WinRE khổng lồ perform the recovery. You will need lớn piông chồng your language first and there will then be an option on the first screen lớn “Recover from a drive.”Managing WinREWinRE can help devices recover baông chồng khổng lồ Windows, but, if needed, it can be disabled by opening an elevated comm& prompt & using the reagentc /disable commvà. By disabling WinRE, however, some Windows 10 features may not work, including many outlined in this blog post. Additionally, WinRE will be re-enabled after a feature update is installed as it is a critical part of the update process.Permission & authenticationIf you are a Windows Insider taking flights, you may have sầu seen a behavior change on Windows 10 Insider Preview Build 19536 and later, where the default authentication requirements for WinRE are different. Previously, most tools và actions required local admin credentials but were not able lớn use modern credentials like Windows Hello (face, PIN, fingerprint). This became a big problem with passwordless accounts & Azure Active Directory accounts that weren’t backed up with a local admin account. To address this, we changed the mặc định behavior khổng lồ no longer require local administrator authentication to lớn access WinRE tools.If you manage devices using di động device management (MDM) solutions such as shimatest.shop Endpoint Manager, you can configure the Security/RecoveryEnvironmentAuthentication policy if you would lượt thích lớn require local administrator authentication lớn use WinRE components.Other interesting thingsBooting into lớn RAMWinRE can be installed in the same partition as Windows, but it is usually installed in the Recovery or WinRE tools partition. Regardless of where it is installed, it always runs in the RAM (or RAM disk boot) và is assigned the X: drive. This is important to note because any changes you make khổng lồ X: will not be saved after a reboot.BitLockerDepending on the combination of your entry points lớn WinRE, how BitLocker is configured (auto-unlock), & what WinRE option you select, you may be prompted for the BitLocker recovery key khổng lồ unloông chồng your Windows partition. As an example, when launching a comm& prompt, you will be prompted lớn unlochồng BitLocker. If you skip the unlochồng process, the Windows installation drive will remain locked, but you will have access to lớn the X: drive, where WinRE runs in RAM.BootIM.exeOne potentially confusing thing about WinRE is the implementation of BootIM.exe pháo. Most won’t see a difference, but I want lớn explain how this works. When using the entry point from the lock/login screen and holding the Shift key or Settings > Advanced Startup, Windows 10 is not rebooting inlớn WinRE. Instead, it is entering pre-shutdown & showing the BootIM screen which looks exactly lượt thích WinRE. If you select an option that needs to change the boot flag like Use a device, it saves you one restart because you don"t have sầu khổng lồ start WinRE lớn then restart the system again using a device.You can see this functionality by running BootIM.exe from an elevated command prompt, but a quiông xã tip is lớn open Task Manager beforehvà so you can easily use the Alt + Tab combination & end the task when you are done. If you are a Windows Insider taking flights, you will see a behavior change beginning with Windows 10 Insider Pđánh giá Build 19577 to enable greater accessibility within this experience. As the pre-shutdown behavior doesn’t support Narrator or other accessibility features, BootIM will only be used if WinRE isn’t available. Otherwise, the system will restart directly lớn WinRE and skip BootIM.Partition layoutPrior khổng lồ Windows 10, the recommended partition layout was khổng lồ place the recovery partition before the OS partition. Unfortunately, this made it difficult to update WinRE. For Windows 10, we updated the recommendation to always menu WinRE immediately after the OS partition. Depending on how Windows was originally installed, your partitions may not have this layout.Even with the updated recommendation, OEMs have the flexibility to choose a different partition layout for specific solutions. When installing from USB, the legacy layout was still being used by some partners until it was formally updated in Windows 10, version 20H1. For example, in this screenshot from a newer máy tính, the OEM put an Recovery Partition where it needs khổng lồ go, last in line.

Figure 6. A Disk Management partition layout exampleRecovery partition labelingThe WinRE partition can have any volume label or no label, but the most common labels are WinRE tools, WinRE, or Recovery. The label is subject to lớn change upon update. The status could also say OEM Partition or Recovery Partition.The WinRE partition shouldn’t have sầu a drive letter assigned and any folders or files should not be available for editing. A comtháng misunderstanding is that the recovery partition contains a compressed copy of Windows and that this copy is what is restored during the remix process. This is not the case. This partition only contains WinRE and drivers. The kích thước can vary depending on how it was configured by the OEM (e.g., what languages & drivers were included).
