Can I Retrieve Data from a Corrupted Windows Operating System?

Yes, you can recover data from a corrupted Windows OS. Many users believe it's difficult to access hard disk data without an operating system. However, they are still searching for a solution to recover data when their PC fails to boot. Are you in the same situation? If so, the Data Recovery Wizard tool can address your problem.

Data Recovery Wizard with Bootable Media is primarily developed for data recovery scenarios in the event of any system crashes or startup issues. It effectively retrieves lost data when your computer encounters various booting problems, such as crashes, freezes, or constant rebooting. Additionally, it efficiently helps in recovering data from a dead hard drive.

Let's explore how to retrieve your data from a corrupted Windows 10/8/7 or other versions.

Step 1. Create a bootable disk

Launch the Data Recovery Wizard, select "Crashed PC Recovery", and click "Start Recovery".

Choose an empty USB drive to create the bootable drive and click "Create."

Step 2. Boot your computer from the bootable USB Boot your computer by using the USB drive you made bootable in the previous step. To do this, you'll typically need to access your computer's Boot Menu during startup. The method to access this menu varies depending on your computer's manufacturer, but it's often done by pressing a specific key like F2, F10, F12, or Esc immediately after turning on your computer. Look for a message on the screen that says "Press [key] to enter Setup" or "Press [key] to boot from USB." Once you've entered the Boot Menu, select the USB drive as the primary boot device. After that, your computer will start from the USB drive and load the installation media. Follow the on-screen instructions to begin the installation process for your operating system.

Connect the bootable disk to the non-booting PC and alter your computer's boot sequence in BIOS. For most users, restarting their computer and pressing F2 simultaneously to access BIOS typically works effectively.

Step 2. Right-click "Command Prompt" and select "Run as administrator".

Step 3. Type in the following command: chkdsk e: /f /r /x. (Replace "e" with the drive letter of the partition you wish to repair.)

• chkdsk /f is running to repair any discovered errors.
• chkdsk /r is running to search for bad sectors and recover readable data.
• chkdsk /x is running to forcibly dismount the volume before the utility starts scanning it.

Solution 3: Updating All Device Drivers to the Latest Version

System corruption can indeed occur after a Windows 10 update, often due to incompatibility between hardware and drivers. To rectify this issue, ensure that you update all your device drivers.

Step 1. Navigate to "This PC" > "Manage" > "Device Manager."

Step 2. Expand "Disk drives".

Step 3. Right-click the disk and select "Update driver".

Solution 4: Run the System File Checker (Sfc) Scan to Repair Corrupted System Files

System File Checker is a utility in Windows that enables users to detect and repair corruption in Windows system files. To utilize this tool to scan for and fix any missing or damaged system files, please follow the step-by-step guidance outlined below: 1. Press the 'Windows key + X' on your keyboard. 2. From the menu that appears, choose 'Command Prompt (Admin)' or 'Windows PowerShell (Admin)' if you're using Windows 10 or later. This will open an elevated command prompt with administrator privileges. 3. In the command prompt, type the following command: ``` sfc /scannow ``` 4. Press 'Enter' to initiate the scan. The System File Checker will now scan your entire system for any corrupt system files. 5. The process may take some time, so please be patient. Once the scan is complete, it will automatically attempt to fix any issues it finds. 6. After the scan, you'll receive a message indicating whether any problems were found and if they were successfully repaired. For example: ``` Windows Resource Protection did not find any integrity violations. (It is important to note that Windows Resource Protection could not perform some actions.) ``` or ``` Windows Resource Protection found corrupt files and successfully repaired them. ``` 7. Close the command prompt and restart your computer for the changes to take effect. If the System File Checker fails to fix the issues or if you continue experiencing problems, you might need to seek additional troubleshooting steps or professional assistance.

Step 1. Press the "Windows" key and type "cmd".

Step 2. Right-click "Command Prompt" and select "Run as administrator."

Step 3. Type sfc /scannow into the Command Prompt window and press "Enter" to initiate a full system scan.

If the System File Checker was unable to repair one or more files, you should consider performing a System Restore or a clean installation of Windows. Before proceeding, back up your data without booting into Windows to ensure its safety.
