Boot Device Not Found - Hard Disk 3F0

HP Recommended
HP 15 - 1387WM / HP 15 - F387WM
Microsoft Windows 10 (64-bit)

Hello all! I'm in need of some serious help. I was on a mission to reset my laptop to its factory settings and somehow ended up with a black screen saying "Boot Device Not Found". I've been having issues with the laptop ever since it was gifted to me. It has a tendency to over heat and get a blue screen saying something about watchdog timeout. Then just recently I wasn't able to download any new Windows 10 updates, but at the same time I was able to uninstall any of the updates already done. So that's why I wanted to factory reset. So now here I am, totally lost as to what to do. I've Googled and YouTubed for days and nothing I try is working. I ran the F2 system tests for the memory and both the quick and extended hard drive checks and they all passed. I got into BIOS and changed settings in there, but literally nothing has worked. I ended up getting a screen that told me to Reboot and Select Proper Boot Device as well. I did the Ctrl + Alt + Delete then hitting Esc until another menu popped up. I tried all those options to no avail either. Please help me! I'm so lost and confused! I work from home and really need to get this fixed as soon as possible!!! Thank you guys in advance for your time!

PS- I have a HP 15 laptop with Windows 10, if that helps at all.

@Ang174 I know you've done most of these steps, however, if done in the sequence mentioned below the issue should be resolved, also, please skip the steps you've already done and let me know how that pans out:

Please follow the below steps to identify and resolve this concern:


Step 1: Perform a hard reset

HP Notebook PCs - Performing a Hard Reset or Forced Reset


Step 2: Restore BIOS default settings


Step 3: Test the hard drive using HP PC Hardware Diagnostics UEFI (In your case, Skip to Step 4)


Step 4: Re-seat the hard drive (here's a generic video that shows how to re-seat the drive: Click here) > 3F0 error represent a hardware malfunction, a reseat should help, if it doesn't or you aren't comfortable, please Contact HP as the next step will not help.


Step 5: Perform an HP System Recovery


If none of the above actions resolved the error condition, back up your personal data and then perform an HP System Recovery on the notebook. See one of the following documents for instructions:
