 This will open the Advanced Boot Options menu if you are quick. If Windows tries to load, you'll need to reboot and try again.
 This will load Windows in Safe Mode, which will usually work even if Windows normally shows a black screen.


If Safe Mode will not work, try a Startup Repair.
,,, You may have one or more display adapters listed here.
