Summary

This guide helps you troubleshoot and resolve: How to Perform a Clean Installation of Windows 11. Follow the steps below to fix the issue.

Common Causes

Prerequisites

• A valid Windows 11 product key (if required for your license type)
• A USB flash drive with at least 8GB of storage
• Access to a working PC to download the Windows 11 Media Creation Tool
• Backup of all important data on the target machine

Step-by-Step Instructions

1. Download Windows 11 Media Creation Tool

• Visit the official Microsoft Windows 11 download page.
• Click "Download Now" under the "Create Windows 11 Installation Media" section.
• Run the downloaded `MediaCreationToolW11.exe` file.

2. Create Installation Media

• Accept the license terms.
• Select "Create installation media (USB flash drive, DVD, or ISO file) for another PC."
• Choose your language, edition (Windows 11), and architecture (64-bit recommended).
• Select "USB flash drive" and choose your connected USB drive.
• The tool will download Windows 11 and create the bootable USB drive.

3. Boot from USB Drive

• Insert the created USB drive into the target PC.
• Restart the PC and enter the BIOS/UEFI settings (typically by pressing F2, F12, DEL, or ESC during startup).
• Change the boot order to prioritize the USB drive.
• Save changes and restart the PC.

4. Install Windows 11

• When the Windows Setup screen appears, select your language, time, and keyboard preferences.
• Click "Next" and then "Install Now."
• Enter your product key when prompted (or select "I don't have a product key" if you're reinstalling on a previously activated machine).
• Select the edition of Windows 11 you wish to install (must match your license).
• Accept the license terms.

5. Partition Selection

• On the "Which type of installation do you want?" screen, select "Custom: Install Windows only (advanced)."
• You'll see a list of existing partitions.

- Warning: Deleting partitions will erase all data on them.

• Select each partition on the main drive (usually Drive 0) and click "Delete" until only unallocated space remains.
• Select the unallocated space and click "Next." Windows will automatically create the necessary partitions and begin installation.

6. Initial Setup (Out of Box Experience - OOBE)

• After installation, the PC will restart. Remove the USB drive when prompted to avoid booting from it again.
• Follow the on-screen prompts to:

- Select region and keyboard layout

- Connect to a Wi-Fi network

- Sign in with a Microsoft account (or create a local account if preferred)

- Set up a PIN

- Configure privacy settings (Location, Diagnostic data, etc.)

- Customize Cortana and other preferences

Post-Installation

• Windows Update: Immediately check for and install all available updates via Settings > Windows Update.
• Drivers: Install necessary drivers (chipset, graphics, network) from the PC manufacturer's website or via Windows Update.
• Antivirus: Ensure Windows Security (Defender) is active and updated.
• Restore Data: Copy your backed-up files back to the appropriate locations.

Troubleshooting

• Boot Failure: Verify BIOS boot order is set correctly.
• Installation Fails: Check that the installation media is not corrupted; recreate it if necessary. Ensure the PC meets minimum system requirements.
• Activation Issues: Use the Activation Troubleshooter in Settings > Activation if the digital license isn't automatically detected.
