I recently installed windows 8.1 from 7 and the installation process was smooth and seemed to work just fine. However, once I shutdown and booted up again I got a blank screen right after the windows logo appeared. I can change the volume and brightness at the blank screen but not anything else. I have tried loading safe mode and using shift + f8 but nothing happens. I have a dell studio 1558 and I installed windows 8.1 from a thumb drive if that makes any difference. Ive also tried booting from the usb which has the windows 8 installation but it said there was an issue. If someone could help me out I would appreciate it a lot.
