Recently, I experienced an annoying issue on my HP Omen gaming PC. When I turned on my PC, it started normally and on the booting point, it bugged and the screen was dark. I was confused and didn't understand why this suddenly happened.
I started trying to figure out what that issue can possibly be. I turned off the PC and waited for some hours then turned it on again but it still did the same.
The first thing I did was a BIOS troubleshoot since HP laptops come with system recovery option. I held the windows and B key on my keyboard then pressed the power button for 2-3 seconds till the PC blipped.
What I was attempting to do here was to restore the BIOS backup on my hard drive since I thought it was a BIOS issue. I completed the necessary steps for that and then performed a BIOS recovery.
When the PC restarted to save the changes, this is where I faced the issue "boot device not found please install an operating system on your hard disk 3f0 error".
What first blipped into my mind was that my operating system was either corrupted by a virus or my hard drive had an issue. I performed a hardware test and my drives had no issue.
At this stage, I was sure I'm facing a software issue. I applied a trick which worked out perfectly and I got my PC up and working up again. What was the trick I applied? You will get the tricks I used as you continue reading.

All still refer to the same problem and can be fixed the same way.
