- Restart your device several times, then try again.

If the setup still fails, try switching to an IDE-based hard disk.
- Launch a clean boot, restart your device, then try again.
- If you are upgrading to Windows 10 using the .ISO file, make sure to disconnect from your internet connection during setup. If your device is connected by Wi-Fi or through LAN, you need to disable both before attempting to run a system upgrade again.
