In the right panel, find the parameter named setup.exe.
In the Registry Editor, go to the reg key HKEY_LOCAL_MACHINE\SYSTEM\Setup\Status\ChildCompletion.
In the command prompt that appears, start the Registry Editor using the regedit command. On some laptops, you need to use a keyboard shortcut Shift+Fn+F10, or disable the System Configuration -> Action Keys Mode = Disabled option in the BIOS settings Press Shift + F10 right on the screen with the error. To fix the problem, you don’t need to close the error message or click OK: To install Windows, click “OK” to restart the computer, and then restart the installation.Īs I said before, if the “computer restarted unexpectedly” error occurs, neither the click on the OK button nor the restart of the Windows installation wizard helps – the error still gets looped. The computer restarted unexpectedly or encountered an unexpected error.
