What are the steps to reinstall Windows 10?

1. Back Up Your Important Files

Before you begin the reinstallation process, it’s crucial to back up all your important files. This includes documents, photos, videos, music, and any other data you don’t want to lose.

  • Copy your files to an external hard drive or USB drive.
  • Use a cloud storage service like OneDrive, Google Drive, or Dropbox.
  • Consider creating a system image backup for a complete snapshot of your current setup (though this isn’t strictly necessary for a clean reinstall).

2. Choose Your Reinstallation Method

Windows 10 offers several ways to reinstall the operating system. Here’s a breakdown:

  • Reset this PC (Keep my files): This option reinstalls Windows while keeping your personal files intact. It’s the least drastic option and suitable for fixing minor issues. To do this:
  1. Go to Settings > Update & Security > Recovery.
  2. Click Get started under “Reset this PC.”
  3. Choose Keep my files.
  4. Follow the on-screen instructions.
  • Reset this PC (Remove everything): This performs a clean installation, removing all your personal files, apps, and settings. It’s ideal for a fresh start or when selling your PC. To do this:
  1. Go to Settings > Update & Security > Recovery.
  2. Click Get started under “Reset this PC.”
  3. Choose Remove everything.
  4. Follow the on-screen instructions.
  • Clean Install with Installation Media: This method involves booting from a USB drive or DVD containing the Windows 10 installation files. It offers the most control and is recommended for advanced users.

3. Create Windows 10 Installation Media (If Needed)

If you’re opting for a clean install, you’ll need to create installation media.

  1. Download the Media Creation Tool from the Microsoft website.
  2. Run the tool and accept the license terms.
  3. Choose “Create installation media for another PC.”
  4. Select your language, edition, and architecture (usually 64-bit).
  5. Choose either a USB flash drive (at least 8GB) or an ISO file to burn to a DVD.
  6. Follow the on-screen instructions to complete the process.

4. Boot From the Installation Media (For Clean Install)

  1. Insert the USB drive or DVD into your PC.
  2. Restart your computer.
  3. Enter the BIOS/UEFI settings (usually by pressing Delete, F2, F12, or Esc during startup – check your motherboard manual).
  4. Change the boot order to prioritize the USB drive or DVD drive.
  5. Save the changes and exit BIOS/UEFI.
  6. Your computer will now boot from the installation media.

5. Install Windows 10

  1. Select your language, time and currency format, and keyboard input method.
  2. Click “Install now.”
  3. Accept the license terms.
  4. Choose “Custom: Install Windows only (advanced)” for a clean install.
  5. Select the partition where you want to install Windows. If you’re starting fresh, you can delete all existing partitions and create a new one.
  6. Follow the on-screen instructions to complete the installation.

6. Configure Windows 10

  1. After the installation, Windows 10 will guide you through the initial setup process.
  2. Connect to a network.
  3. Choose whether to use a Microsoft account or a local account.
  4. Configure your privacy settings.
  5. Follow the on-screen instructions to personalize your experience.

7. Install Drivers and Updates

  2. Go to Settings > Update & Security > Windows Update and check for updates. Install all available updates to ensure your system is secure and stable.

Tips

  • Keep your product key handy: You might need it during the installation process.

  • Be patient: The reinstallation process can take some time, so be patient and don’t interrupt it.
