When attempting to reset or reinstall Windows 10 via the "Reset this PC" option, you may see an error message or the process may fail to start.
**Possible Causes:

**Troubleshooting Tips:
- **Run Automatic Repair: If you cannot reset the PC normally, try booting into the **Windows Recovery Environment (WinRE) and select **Startup Repair.
- **Check Disk Space: Make sure your system partition has enough free space to complete the reinstallation. You can use a disk cleanup tool or external storage to free up space.
- **Use the Command Prompt: In WinRE, open **Command Prompt and run the following command to repair the system files:
sfc /scannow
This will check for any corrupted files and attempt to fix them.
