Good news everyone, I finally found a solution. I had to restart my computer and hold down the F8 key before the HP logo appeared on my screen. This put my computer in safe mode where I was given several options to recover my computer. I simply did the 'reset my PC' option and after a while, Windows 10 reinstalled itself on my computer. Thankfully, all of my files were recovered and my PC had successfully updated itself and I was able to access my computer once again.
In fact, I'm currently using Windows 10 on my Laptop as we speak! Thanks for the help anyway.
