Black Screen on BIOS Setup Utility and Boot Device but not System Diagnostics

HP Envy Ultrabook 4-1030us

I recently tried to install Windows 10 on my laptop (came with Windows 7 originally) but after the update starting up the laptop opens up on a black screen with the backlight on. However, I can hear the fan spinning and the LED indicators for power, wireless and hard disk usage are all on.


I tried to enter BIOS by pressing the ESC key on startup and it opened the Startup Menu fine. However, when I press F10 in the startup menu to access the BIOS Setup, the black screen with backlight on occurs again. When I do F9 for Boot Device Options the same thing happens. Pressing F1-System Information works fine and F2 opens the system diagnostics screen with 4 options: Memory Test, Hard Drive Check, Language, Exit.


The Windows 10 installation wiped out the HP_TOOLS partition so I downloaded the HP PC Hardware Diagnostics 3-in-1 USB Key. When this flash drive is plugged in and I attempt to access F2-System Diagnostics on the Startup Menu it opens up a white screen with buttons for various hardware tests which I presume is what's supposed to happen with the HP Diagnostics USB.


I've tried resetting the power by holding down the power button for 15 seconds but the same thing happened.


I've tried recovering the BIOS by starting up with the Windows + B keys pressed. In this case, there is a black screen too except this time the backlight is off. The fan still spins and the LED lights still turn on. Even after waiting for 5 minutes nothing seems to happen.


I've also tried Windows + V keys on startup. In this case the laptop beeps loudly ~12 times and a black screen with backlight occurs again.


I've tried updating the BIOS with the diagnostics flash drive to version F.25. The update seemed to occur normally and after the update F.25 shows up in the System Information screen but the problem persists.


What is going on? Why can I only access some parts of the startup menu but not F10-Bios Setup or F9-Boot Device Options? Why can't I boot into anything except the HP Diagnostics USB?
