Error 3F0, Boot Device Not Found

HP Recommended
HP Spectre x360 - 13t-ae000 CTO
Microsoft Windows 10 (64-bit)

When I try to boot up my laptop I get a message that says:

 

Boot Device Not Found

Please install an operating system on your hard disk

Hard Disk (3F0)

 

After a couple of attempts to restart the computer I can eventually access the OS, but the next session when I try to turn on my computer from sleep mode I get the error message again.

 

I've been looking up solutions online and nothing has been able to fix this issue. I already tried all of the following:

- a hard reboot of the computer

- uninstalling recent windows updates

- performing a system diagnostics on the hard drive (no errors were found)

- updating drivers

- using System File Checker through command prompt [sfc /scannow]

- running Windows Memory Diagnostic

- DISM through command prompt [Dism /Online /Cleanup-Image /RestoreHealth] 

- reinstalling Windows

 

Some of these solutions were helpful because my device kept shutting down due to a BSOD, but none of these solutions have been able to address the current issue I'm having.

 

The only online suggestion that helped with regards to the boot error was a recommendation to enable Legacy Support in BIOS. When I tried this it was able to fix the Boot Error, but one problem was replaced with another. My notebook would start getting a BSOD that displays:

 

stop code: WHEA_UNCORRECTABLE_ERROR

 

Because of this I've decided to leave Legacy Support disabled.

 

I've tried everything and I don't know what to do. Hopefully someone can help me figure out what's wrong with my notebook.

I'm guessing since no one has replied that I should just go ahead and take my laptop to a repair shop

In my case, reseating the SSD ended up solving the issue, so if nothing else has worked I would say to give that a shot. As soon as you remove the bottom cover it should be accessible, so it's not to much trouble.
