Method 2: Reinstalling Windows 10 with Installation Media

This method is particularly helpful if your system experiences significant issues or fails to boot. Here’s how to do it:

  1. Prepare Installation Media
    Connect a USB flash drive or insert a DVD with a minimum of 8GB storage (16GB recommended) for additional data.

  5. Choose USB Flash Drive or ISO File
    Opt for the USB flash drive or select an ISO file to burn later onto a DVD.

  6. Ready Your Installation Media
    Follow the prompts to convert your USB drive into a bootable installation medium. This process may take some time based on your internet connection.

  7. Install from USB
    Restart your PC with the USB drive attached; your computer will recognize it and start the installation process.

Reinstalling Windows from BIOS

If the installation doesn’t start automatically after restarting, you may need to adjust the boot order via your BIOS settings. Here’s how:

1. Change the Boot Order

  • Restart your computer and press the specific key that allows you to enter BIOS (often F2, F12, Del, or Esc).
  • Navigate to the Boot tab and ensure the USB option is prioritized.

2. Adjust UEFI Settings

If you don’t see the USB option:

  • Enter BIOS again, navigate to the Security tab, and set Secure Boot to Disabled.
  • Go to the Advanced tab, click on System Configuration, and change Boot Mode to Legacy.

Note: Remember to revert to the original Boot Mode once the reinstallation is complete.
