Fixing Windows Installation on UEFI Systems: A Step-by-Step Guide

UEFI (Unified Extensible Firmware Interface) is a newer firmware platform that offers improved security, speed, and flexibility compared to traditional BIOS systems. However, Windows installation can sometimes encounter issues when running on UEFI systems. Don’t worry, this guide will walk you through the steps to troubleshoot and fix common problems.

Pre-Requisites:

• Your computer should have a UEFI firmware.

• You should have the Windows installation media (USB or CD/DVD).

• Basic knowledge of command-line interfaces.

Step 1: Boot from the Installation Media

• Insert your Windows installation media into your computer’s USB drive or DVD drive.

• Restart your computer and enter the BIOS settings (usually by pressing F2, F12, Del, or Esc during boot-up).

• Save changes to exit the BIOS setup.

Step 2: Identify UEFI Firmware Mode

• In the BIOS setup, look for an option that says “Boot” or has a UEFI logo.

• If you see options like “Legacy Boot” or “Firmware,” select it and continue to the next step.

Step 3: Set UEFI Mode to Compatibility Mode (if necessary)

• Look for an option called “Compatibility Mode” or “UEFI Compatibility” in the BIOS setup.

• Select this option, if available.

• Save changes to exit the BIOS setup.

Step 4: Boot from Windows Installation Media

• Restart your computer and enter the BIOS settings again.

• Set the UEFI firmware mode to “Compatibility Mode” (if selected) or leave it as UEFI.

• Save changes to exit the BIOS setup.

Common Issues and Solutions:

1. Unable to Install Windows

• Check that the installation media is not damaged or corrupted.

• Ensure that you have a stable internet connection during the installation process.

• Try installing Windows from a different USB drive or CD/DVD.

2. UEFI Firmware Not Detected

• Verify that your computer has a UEFI firmware and check the BIOS settings for any issues.

• If you’re using an older motherboard, try upgrading to a newer one with better support for UEFI systems.

• Update your BIOS to the latest version (if available) through your motherboard manufacturer’s website.

3. Installation Failed Due to Missing Drivers

• Check that all necessary drivers are installed on your computer.

• Download and install any missing drivers from Microsoft’s Support Website or your motherboard manufacturer’s website.

• Reboot your computer after installing the drivers.

4. Error Messages During Boot-up

• Check for updates in Windows and ensure that your operating system is up-to-date.

• Run a System File Checker (SFC) scan to repair corrupted system files:

sfc /scannow

• If you encounter any error messages during boot-up, try running the System Restore Tool:

msdt.msc

Conclusion:

Troubleshooting Windows installation on UEFI systems requires patience and persistence. By following these steps and solutions, you should be able to identify and resolve common issues that may arise during the process. Remember to always back up your important files before attempting any system updates or installations.
