Hp Laptop problem

[N-12_]

I wanted to download a video editor for my presentation video. But for my curiosity, I started to download 2 softwares at once. I left the computer without turning it off! After half an hour, I returned. But when I opened it, it showed "Boot device not found, download an operating system (3FO). Now no one can fix it, and I do many programming classes, so I need my laptop all the time. What can I do to fix it? I also followed some of google's instructions. But it doesn't do anything. So, please someone help me!

What was that? Your contribution to solve the problem is poor.

List your BIOS settings of the "System Configuration" and the BIOS "Boot Options"

This issue is often due to a failing drive.

So, let's check that first, because if it is failing, it would need to be replaced and there is no point then in doing anything else until we confirm that.

If your PC is new enough to support UEFI, you can use these steps to test the HDD (Hard Disk Drive): http://support.hp.com/us-en/document/c00439024

If not, to check the HDD you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu
3) Press the Function key for testing the hard drive (usually F2) and let it run.

If the drive checks out OK, then report that and I can provide you options for reinstalling Windows on your PC.

Please note that if your model has an SSD instead of an HDD, these diagnostics might not work properly.

You don't have to do that if you really  run a 32-Bit OS.
