Alternatively, tools like Driver Booster or DriverPack Solution can simplify the driver update process, allowing for hassle-free updates.
Check Storage Space
Insufficient storage space can also lead to installation errors. Make sure your PC has at least 64GB of available space to facilitate the installation of Windows 11. Verify that sufficient space exists on a single partition.
Conduct SFC And DISM Scans

- This process should ideally resolve the error.
If the SFC scan does not fix the issue, consider running a DISM (Deployment Image Servicing and Management) scan by following these steps:
- Run Command Prompt as an administrator, as outlined above.
- Type and execute the command:
Dism /Online /Cleanup-Image /RestoreHealth.
- Allow the process to complete, and the issue should now be resolved.
