Here’s a comprehensive guide to troubleshooting Windows installation issues:

Pre-Installation Checks

• Check System Requirements: Ensure your computer meets the minimum system requirements for installing Windows.

• System Disk Space: Verify that you have enough free disk space on your computer.

• Internet Connection: Check that there is an active internet connection, as Windows may require a stable internet connection to download and install.

Installation Issues

• No Installation Disc: If you’re trying to install from a USB drive or CD/DVD, ensure it’s properly connected and recognized by the computer.

• Blue Screen of Death (BSOD): Restart your computer and enter Safe Mode with Networking.

• Error Messages: Check the Event Viewer logs for error messages, such as «System File Checker failed» or «Windows cannot be installed.»

• Failed Installation: If installation fails, try again from the Start menu.

Post-Installation Issues

• BIOS Settings: Ensure your computer’s BIOS is set to boot into Windows.

• Driver Updates: Verify that all drivers are up-to-date and compatible with the latest version of Windows.

• Network Connection: Check that your network connection is stable, as some issues may be related to network connectivity.

• User Account Control (UAC): Ensure User Account Control is enabled and set to prompt for admin privileges.

Troubleshooting Steps

• Run a System File Checker (SFC) scan: Use the Command Prompt to run SFC and check for corrupted system files.

• Disable and Re-enable the Service: If you’ve installed multiple updates, try disabling them one by one and see if it resolves the issue.

• Check for Windows Updates: Ensure all available Windows updates are installed.

• Reinstall Driver Drivers: If driver issues persist, try reinstalling drivers or updating to the latest version.

Advanced Troubleshooting

• System Restore: Use System Restore to revert your computer back to a previous point when the issue first appeared.
