I try the" Last known good configuration" it go to starting window for a minute then it go back to window recovery error screen. I try the safe mode it start loaded:window system 32\driver then it go to " setup is preparing your computer for first use screen." Then the error window pop up saying" windows cannot complete installation in safe mode. To continue installing Windows, restart the computer". I click enter. Then it go back to starting Windows. It keep running at that screen and the fan is running very loud. The laptop is getting very hot. It just going no where. Appreciate if you can help.
