Remove Peripheral Devices

To fix a Windows 10 upgrade failed installation error, one common issue could be with peripheral devices connected to your computer. To troubleshoot this problem, remove all peripheral devices such as printers, scanners, headphones, and docking stations from your PC. Sometimes, conflicts with these devices can cause installation errors.

Once you have disconnected all external devices, try to reboot your computer in safe mode. This can help isolate the issue and allow you to proceed with the installation without any interference from third-party devices. To boot into safe mode, restart your computer and press the F8 key repeatedly until the Advanced Boot Options menu appears.

After entering safe mode, attempt to reinstall the Windows 10 upgrade. If the installation is successful, you can then reconnect your peripheral devices one by one to identify which one was causing the error. This process can help you pinpoint the specific device that was causing the installation problem.

If you continue to experience issues with the Windows 10 upgrade, you may need to update or reinstall the device drivers for your peripherals. Outdated or incompatible drivers can sometimes prevent new installations from completing successfully. You can update drivers through Device Manager in the Control Panel or by downloading the latest drivers from the manufacturer’s website.

Clear Attributes of Installation Folder

When troubleshooting a failed Windows 10 upgrade installation error, it is important to pay attention to the attributes of the installation folder. The installation folder is where all the necessary files are stored during the installation process and any issues within this folder can lead to errors.

Check the Attributes: Start by navigating to the installation folder using File Explorer. Right-click on the folder and select “Properties” from the context menu. Look for any attributes that might be causing the installation error, such as read-only status or permission restrictions.

Modify Attributes: If you find that the installation folder has the read-only attribute enabled, you will need to change it. Click on the checkbox next to “Read-only” to uncheck it and apply the changes. Make sure that all necessary permissions are granted to the folder to avoid any further errors.

Verify Contents: Double-check the contents of the installation folder to ensure that all the required files are present. If any files are missing or corrupted, you may need to re-download the installation files or use a different source to complete the upgrade process.

It is essential to keep the installation folder clean and free from any unnecessary files or folders that could interfere with the installation process.

Uninstall Language Packs

  • Press Windows key + I to open Settings
  • Click on Time & Language
  • Select Language from the left pane
  • Click on a language you want to remove

Rebuild Boot Configuration Data

If your Windows 10 upgrade installation has failed due to an error, one possible solution is to rebuild the Boot Configuration Data (BCD). This can help fix any issues related to booting up your system.

To rebuild the BCD, you’ll need to access the Command Prompt. You can do this by pressing the Windows key + X and selecting “Command Prompt (Admin)” from the menu.

Once in the Command Prompt, type the following command and press Enter: bootrec /rebuildbcd. This command will scan your system for installations compatible with Windows and add them to the BCD.

After running the command, restart your computer to see if the issue has been resolved. If the Windows 10 upgrade installation error persists, you may need to try other troubleshooting steps or seek further assistance from Microsoft support.

Perform a Clean Boot Installation

To fix a Windows 10 upgrade failed installation error, you can try performing a clean boot installation. This process helps eliminate software conflicts that may be causing the installation issue.

Here’s how to do it:

1. Press the Windows key + R to open the Run dialog box.
2. Type “msconfig” and press Enter to open the System Configuration window.
3. In the System Configuration window, go to the Services tab.
4. Check the box next to “Hide all Microsoft services” to hide the Microsoft services.
5. Click on “Disable all” to disable all non-Microsoft services.
6. Next, go to the Startup tab.
7. Click on “Open Task Manager.”
8. In the Task Manager window, disable all the startup programs by right-clicking on each one and selecting “Disable.”
9. Close the Task Manager and go back to the System Configuration window.
10. Click on “OK” and then select “Restart” to restart your computer in a clean boot state.

Performing a clean boot installation can help you identify the software that may be causing the installation error. Once you have successfully installed Windows 10 in the clean boot state, you can gradually enable the services and startup programs to pinpoint the culprit.

Repair Corrupted System Files

First, open Command Prompt with administrative privileges by searching for “cmd” in the Start menu, right-clicking on Command Prompt, and selecting “Run as administrator.”

Next, type the following command and press Enter: sfc /scannow. This will scan your system for corrupted files and attempt to repair them automatically.

The System File Checker tool may prompt you to restart your computer to complete the repair process. If so, go ahead and restart your computer.

After the repair process is complete, check if the Windows 10 upgrade installation error has been fixed. If not, you may need to consider other troubleshooting steps or seek further assistance.

Remember to regularly run the System File Checker tool to ensure that your system files are in good condition and prevent future issues with your Windows 10 installation.
