How To Repair Windows 7 Without Losing Data

Windows 7, like any other operating system, can sometimes encounter problems that require a repair. If you’re
facing issues with your Windows 7 installation, you might be worried about losing your data during the repair
process. Fortunately, there are ways to repair Windows 7 without losing data. In this blog post, we’ll show
you how to perform a repair installation (also known as an in-place upgrade) of Windows 7 without losing any
of your files or settings.


  • A Windows 7 installation disc or a bootable USB drive with the same version and edition of your current
    installed Windows 7 (for example, if you have Windows 7 Home Premium 32-bit, you’ll need the same version
    and edition).
  • Make sure you have the latest backups of your important files and data. Although this method should not
    affect your data, it’s always a good idea to have a backup just in case something goes wrong.
  • Your Windows 7 product key. You can usually find this on a sticker attached to your computer or in the
    documentation that came with your PC.

Follow these steps to perform a repair installation of Windows 7:

  1. Insert your Windows 7 installation disc or connect the bootable USB drive to your computer.
  2. Restart your computer and press the appropriate key to enter the BIOS. This key varies by manufacturer, but
    it’s often F2, F10, F12, or Delete.
    Check your computer’s documentation or the manufacturer’s website for the correct key.
  3. In the BIOS, go to the Boot options and set your computer to boot from the installation media (CD/DVD or

  6. Read and accept the license terms, then click “Next.”
  7. On the “Which type of installation do you want?” screen, choose “Upgrade.”
  8. Windows will now check for compatibility issues. If any are found, you’ll need to address them before
    continuing with the repair installation.
  9. Once any compatibility issues have been resolved, the repair installation will begin. This process may
    take some time, so be patient.
  10. After the repair installation is complete, your computer will restart. Follow the on-screen instructions to
    complete the setup process.
  11. Once you’re back in Windows 7, check to make sure your files and settings are still intact. If everything
