Unable to boot from hard drive, boot device but found

[Babø]

I was trying to perform a factory reset using HP Recovery Manager on my laptop since the regular method in the Windows 10 settings had been failing me, always starting and stopping at about 6% to undo changes informing me there was something wrong.

I finally found and opened HP Recovery Manager and began to try to reset my device that way without backing up anything at all for a completely wiped drive. However, right after I clicked for it to start it stopped and said there was an error. It read that it failed and read error Oxefffff23 I believe. And after I clicked cancel it brought me to the familiar screen of "Boot Device Not Found" and "Hard Disk (3F0)".

I've tried troubleshooting and I've run a quick test and my hard drive passed the tests, I've opened my BIOS and made sure legacy boot was off and I made sure my boot source priorities order was correct. I don't know what else to try or how to fix this and need help.

The error you were getting almost always indicates a failing hard drive.

If your PC is new enough to support UEFI, you can use these steps to test the hard drive: http://support.hp.com/us-en/document/c00439024

If not, to check the drive 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.

I mentioned that I already tested the hard drive and it passed those tests. 

The real problem was as I feared, when the reset process got aborted the OS became corrupt and a simple external recovery drive was all I needed.

I solved the problem myself.
