Here’s a step-by-step guide on how to fix Windows installation errors using system diagnostics:

Prerequisites:

• Ensure you have the latest service packs and updates installed.

• Make sure your system is connected to the internet.

• Run the System File Checker (SFC) tool to scan for corrupted system files.

Step 1: Run System File Checker (SFC)

• Open Command Prompt as Administrator.

• Type sfc /scannow and press Enter.

• The SFC tool will scan your system and replace any corrupt system files.

Step 2: Run DISM

DISM stands for Deployment Image Servicing and Management. It’s used to repair or remove corrupted system images, such as the Windows installation media.

• Open Command Prompt as Administrator.

• Type dism /online /cleanup-image /restorehealth and press Enter.

• If you want to remove a corrupted system image, type dism /online /removeimage /id:your_image_id. Replace your_image_id with the actual ID of your system image.

Step 3: Run Check System for Damaged Files

• Open Command Prompt as Administrator.

• Type chkdsk C: and press Enter, replacing C: with the drive letter of your Windows installation media (usually C:).

Step 4: Run System Restore

System Restore allows you to restore your system to a previous point in time when it was working correctly.

• Open Control Panel.

• Click on «System and Security».

• Click on «System».

• Click on «Family Safety» (if installed).

• If you want to restore your system, click on «Restore the system now». Follow the prompts to select a restore point from which you can create a restore image.

Step 5: Check Event Viewer

Event Viewer logs errors and warnings about your system.

• Open Event Viewer by searching for it in Start.

• Click on «Windows Logs».

• Find the error or warning you’re looking for.

• Look for any error messages related to Windows installation.

Step 6: Run the System Recovery Tools

If none of the above steps work, try running the System Recovery Tools:

• Open Control Panel.

• Click on «System and Security».

• Click on «Windows Recovery» (if installed).

• Click on «Recovery options».

Choose the option that works best for your situation.

Troubleshooting Tips:

• If you’re experiencing installation errors, try running a Windows installation media to see if it resolves the issue.

• If you’ve updated or changed your system settings recently, check if it’s causing any conflicts with the installation process.

• If none of the above steps work, try reinstalling Windows using the «Reinstall Windows» option in Control Panel.

By following these steps and troubleshooting tips, you should be able to identify and fix common Windows installation errors.
