My laptop monitor went bad so I completely disconnected it from the laptop and attempted to use it as a desktop with an external monitor through HDMI.
I was not able to see BIOS or see booting options on the extended monitor. Windows was crashing. So I went ahead and I installed Linux and it finally was able to show Linux through the extended monitor.
I wanted to get Windows back into the system but since I wasn't able to load up booting options or BIOS, I took out the HDD and connected it to an adapter and externally installed windows on it. I tried it on another system and I am able to boot Windows. But, when I put it back on the HP laptop, the extended monitor is black all the way to the log in screen (I am able to tell because of the sounds) I have tried F4, Windows Key+P to try to bring display to the monitor, but no success.
