Error when installing Windows 8 "The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed."

If your getting this error then when presented with the message :

1. Press SHIFT+F10
2. In the black command window type : regedit  & enter
3. Find : HKLocal/SYSTEM/SETUP/STATUS
4. Double click on ChildCompletion and change the data from 1 to 3
5. Press OK on the initial error message
