I bought my Pavilion 17-e101ed notebook about 9 months ago and since 2 months I'm stuck at a black screen right after the UEFI boot screen (HP logo). I tested all of my hardware (no problems) and I even reinstalled Windows 8.1. Also, no errors (LEDs, sounds) are shown/heard. The only thing that has changed is the LCD screen, which has been replaced after it broke. I can't think of anything else that could have caused the problem.
The weird thing is that I am able to run Ubuntu without problems. However, I need to switch back to Windows, because I need to run software for school that can't run through Wine.
I haven't been able to install an older version of Windows (Windows Vista or 7), since everytime I want to enable Legacy Mode (and disable Secure Boot) my BIOS goes corrupt.
Several IT workers have looked through the notebook and couldn't find the problem. Hopefully you can find the right solution.
