Protect your files first, then use Windows Recovery Environment tools in order: Startup Repair, Safe Mode, System Restore, and update removal before trying Command Prompt, Reset this PC, or a clean installation. Reset options can remove applications, settings, or personal files, so choose them only after checking what each option preserves. ## Before you start, protect your files and identify the failure If Windows still starts, copy your important files before attempting repairs. Use an external drive or a trusted cloud service. Include files from Desktop, Documents, Pictures, Videos, Downloads, and any application-specific folders. If Windows starts only intermittently, copy the most valuable files first instead of trying to create a perfect backup. If Windows will not start normally, try Safe Mode or use another computer to create recovery media. You can also remove the drive and connect it to another computer, but do this only if you know how to handle the hardware safely. A backup is not complete until you can open a few copied files from the destination. Before you start, have these items ready: - Your Windows sign-in password and, if possible, an administrator account. - The BitLocker recovery key, if drive encryption is enabled. Check your Microsoft account, your organization’s account, a saved printout, or the location where your administrator stores recovery keys. - A working computer and a USB drive if you may need installation or recovery media. - Product keys, license details, or installer files for applications you cannot easily replace. - The name and approximate date of a recent driver, Windows update, or application change. Disconnect nonessential USB devices, docks, printers, external drives, and memory cards. Leave the keyboard, mouse, display, network connection if needed, and the drive containing Windows connected. A faulty peripheral can prevent startup or cause repeated crashes. [Check the basic symptoms](https://techbytefix.com/basic-troubleshooting-skills/) before treating this as a Windows problem. If the PC has no lights, fans, display, or response, check the power cable, charger, outlet, and monitor first. Repeated clicking from a drive, a burning smell, sudden shutdowns under load, or memory-related errors can point to hardware. If the firmware screen cannot detect the Windows drive, recovery tools may not be able to fix it. Stop repeated startup attempts if the drive appears to be failing. Continued use can make data recovery harder. ![A Windows PC is connected to an external drive for backing up personal files.](https://tse1.mm.bing.net/th?q=Windows%20PC%20with%20external%20backup%20drive&w=624&h=352&c=7) ## Try these Windows recovery options from least destructive to most drastic Windows Recovery Environment, or WinRE, contains repair tools that run outside the normal desktop. To enter it, turn on the PC and interrupt startup by holding the power button when Windows begins loading. Repeat this only as needed; after several interrupted starts, Windows usually opens **Automatic Repair**. You can also hold `Shift` while selecting **Restart** from the sign-in screen or Start menu. Choose **Advanced options** to see the recovery tools. Use the tools in this order. The exact labels can differ slightly between Windows versions. 1. Select **Startup Repair** under **Troubleshoot > Advanced options**. Let it examine boot files and startup configuration, then restart when prompted. This is the first choice when Windows fails before the sign-in screen or displays a startup error. 2. Return to **Advanced options**, select **Startup Settings**, choose **Restart**, and then press the key for **Safe Mode** or **Safe Mode with Networking**. Safe Mode loads a limited set of drivers. If it starts, remove a recently installed driver or application, undo a recent configuration change, and copy any remaining files. Restart normally afterward to test the change. 3. Open **System Restore** from **Advanced options** and choose a restore point created before the problem began. System Restore rolls back system files, drivers, registry settings, and installed programs recorded in that restore point. It does not normally remove personal files, but applications and drivers installed after the selected point may be removed. Restore points may be missing or disabled. 4. Choose **Uninstall Updates** under **Advanced options** if the problem started immediately after Windows installed an update. Try the latest quality update first. If that does not help and the option is available, Windows may also offer removal of a feature update. Do not interrupt the process while it works. 5. Use **Command Prompt** only when the earlier tools fail and you have a specific repair to make. Drive letters in WinRE can differ from those in normal Windows, so do not assume the Windows volume is `C:`. Inspect the volumes with `diskpart`, then `list volume`, followed by `exit`. After identifying the Windows volume as `C:`, you can check protected system files with: ```cmd sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows ``` Command Prompt A file-system check may help when the drive has errors, but it can take time and is not a substitute for a backup: ```cmd chkdsk C: /f ``` Command Prompt Do not guess the drive letter or run disk commands against a volume containing the wrong data. If BitLocker is enabled, WinRE may ask for the recovery key before it can access the Windows volume. ![A Windows PC displays the Startup Repair option in the recovery environment.](https://tse1.mm.bing.net/th?q=Windows%20PC%20showing%20Startup%20Repair%20screen&w=624&h=352&c=7) ## If Windows still will not start, use a recovery drive or Reset this PC Use recovery or installation media when WinRE on the internal drive is missing, damaged, or unable to repair startup. On another Windows computer, create official Windows installation media on a USB drive, or use a recovery drive that was created for the affected PC. Boot the malfunctioning computer from that USB by opening its firmware boot menu, then select **Repair your computer** instead of installing Windows immediately. This provides access to WinRE tools even when the internal recovery partition does not work. A recovery drive can also reinstall or restore Windows, but its available options depend on how it was created and on the computer manufacturer. It may not contain your personal files or every application driver. If repairs fail, open **Troubleshoot > Reset this PC**. Read each screen carefully before confirming: | Choice | Personal files | Apps and settings | | ----------------- | ------------------------------------------------------------------- | ----------------------------------- | | Keep my files | Preserved in the user profile, though you should still back them up | Removed; Windows settings are reset | | Remove everything | Removed from the Windows installation | Removed; Windows is reinstalled | Reset this PC can remove applications, settings, or personal files. Confirm that your backup is usable before continuing. **Keep my files** is the less destructive reset. It removes installed desktop programs, many drivers, and custom settings, so you will need to reinstall applications afterward. It is not a replacement for a backup, and files stored outside the normal user folders may not be preserved as you expect. **Remove everything** is appropriate when you are preparing to give away the PC, suspect severe software corruption, or need a clean starting point after backing up. Depending on the choices shown, Windows may offer to clean the drive; that takes longer and is different from simply removing files. If the internal recovery image is damaged, choose cloud download when offered and a reliable internet connection is available. If Reset this PC fails repeatedly, installation media may be the safer next step. ![A Windows PC sits beside a USB recovery drive on a desk.](https://tse1.mm.bing.net/th?q=Windows%20PC%20beside%20recovery%20USB%20drive&w=624&h=352&c=7) ## How to confirm the system is repaired without making the problem return After any repair, test a normal restart rather than stopping as soon as the sign-in screen appears. Shut down fully, turn the PC on again, sign in, and let Windows remain idle for a while. Then open the applications and files you normally use. The repair worked if Windows reaches the desktop without Automatic Repair, blue screens, freezes, or repeated restarts. Check these items before restoring every application: - Open Device Manager and look for warning icons, missing devices, or a recently changed driver. - Check Windows Update, but do not install optional drivers blindly if a driver update preceded the failure. - Confirm that your files open and that external storage, audio, networking, display output, and printers work as expected. - Review free disk space and confirm that the system drive is detected consistently. - Reinstall essential applications one at a time, restarting between major changes if the original problem involved crashes. If the PC is stable, create a fresh restore point by searching for **Create a restore point**, opening **System Properties**, selecting the system drive, and choosing **Create**. Restore points are useful for system changes, but they are not backups of personal files. Set up a regular file backup to an external drive or a service you trust, and verify that it can restore files. Keep notes about what fixed the problem and which driver or update was removed. If the same crash returns after one particular installation, that detail can narrow the cause faster than repeating a full reset. ## What to try when every recovery option fails A BitLocker prompt is not necessarily an error. WinRE may require the recovery key after a firmware change, hardware change, or startup repair attempt. Use the key associated with that PC; repeated guesses will not unlock the drive. If you cannot find it, an administrator or organization that managed the computer may be the only source. If System Restore shows no restore points, the feature may have been disabled, its storage allocation may have been too small, or the points may have been removed by disk cleanup or corruption. Use Startup Repair, uninstall a recent update, or restore files from a backup instead. If System File Checker reports that it could not repair some files, the Windows component store or the installation itself may be damaged. From a working Windows session, you can try Deployment Image Servicing and Management before running SFC again: ```cmd DISM /Online /Cleanup-Image /RestoreHealth sfc /scannow ``` Command Prompt (run as Administrator) A repeated blue screen deserves attention to the stop code and the change that preceded it. Remove recently added hardware or drivers, run the hardware maker’s diagnostics, and check memory and storage health. A failing SSD, hard drive, RAM module, overheating system, or power supply will not be fixed by reinstalling Windows. If the drive is unreliable, the PC loses power, or important files exist only on the affected disk, stop experimenting and seek professional data recovery or repair. Once files are safe, a clean Windows installation from official installation media is often safer than repeated resets when the installation is badly corrupted. A clean installation erases the Windows partition, so verify the backup and gather required drivers and account details first. ![A Windows PC displays a BitLocker recovery prompt on its screen.](https://tse1.mm.bing.net/th?q=Windows%20PC%20with%20BitLocker%20recovery%20prompt&w=624&h=352&c=7) ## Conclusion Protect your files first, then work through WinRE from Startup Repair to Safe Mode, System Restore, update removal, and Command Prompt. Use a recovery drive when the internal recovery tools are missing or damaged. Reserve Reset this PC and a clean installation for cases where those repairs fail, and check whether each option keeps or removes personal files. If recovery tools keep failing or hardware symptoms are present, protect the data before attempting more repairs; replacing a failing component may solve the problem more safely than reinstalling Windows. ## Frequently Asked Questions ### Will System Recovery delete my personal files? Startup Repair, Safe Mode, System Restore, and Uninstall Updates are designed to preserve personal files, although System Restore can remove applications or drivers installed after the chosen restore point. Reset this PC has separate \*\*Keep my files\*\* and \*\*Remove everything\*\* choices. Back up your files before using any recovery option. ### What if I cannot find my BitLocker recovery key? Check the Microsoft account used on the PC, saved printouts or files, and any work or school account that managed the device. If an organization owns the PC, contact its administrator. Without the correct key, encrypted data may not be accessible through WinRE. ### Should I reset Windows or replace the drive? Reset Windows when the hardware appears healthy but the operating system remains corrupted. Suspect the drive or another component when it disappears from firmware, produces unusual sounds, reports repeated read errors, causes freezes across different operating systems, or triggers failures during installation. Back up or recover data before replacing it.
