Boot device not found?

[Colo-Sprngs7199]

Hello, hope someone can help me since I am not computer savvy what so ever! 
My HP laptop has been working fine with no issues until today, and it honestly is frustrating. 
Used it to play Netflix last night and then exited out and closed it. Woke up and didn’t try to use it until later that night...it was dead and I plugged it in and tried starting it up.  When I did this, I get a “boot device not found (3FO)”  So as a good millennial I googled it and tried YouTube...

I found people with the same exact screen as me, so I did what they did. Went to system configurations, then to boot settings. Then I enabled legacy support. This worked for many of the individuals, but it did not for me. When I did this he said no boot device not found or something of that nature. Then I made sure to place everything back on default settings and try to start it up again. No matter what I do, I cannot get it to start up properly.

I should also add I did a hard drive check and a memory check, both passed. The quick check and extensive check of the hard drive showed it passed. Since the hard drive passed, that is how I found out about the legacy support option. But this did not work for me like it did for others. Does anyone have advice? My operating system is windows 10. 
Also seen the other post similar to mine but I do not or it does not show oputain? Memory
Thank you for your time,

BH

Hi
PLEASE POST ANY RESULTS.
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat; Re-Connect the AC adapter.

NOW begin checking/testing/proving the Hardware is fit for purpose.
Power on your PC, press ESC (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

IF your HDD was set as GPT/Secure Boot then return it to that state, rather then MBR/Legacy.

It is unlikely, but possible your CMOS/RTC battery is discharged and does not retain the Time and Date between power-ups.

Next would be to try and Repair/Rebuild/Recover/Re-Install using your Back-Ups and Recovery Media.

~~~~~~~~~~~~~

From 2016 onwards there is a possible recovery option via the cloud...
HP Consumer PCs - Using the HP Cloud Recovery Tool (Windows 7 & 10)
https://support.hp.com/us-en/document/c06162205
OR
This First part only works when a valid Recovery Partition is enabled.
If it displays an error message then move onto the Second part,
OR if you have data you wish to try and save using the XCOPY command.
Then create your own Repair/Recovery/Rebuild/Re-install media or buy a set from HP.

Turn off the computer.
Disconnect all connected devices and cables, Media Drives, USB drives, printers, & faxes.
Remove media from internal drives, and remove any recently added internal hardware.
Do not disconnect the monitor, keyboard, mouse, or power cord.
WARNING - ONE WAY ONLY, WIPES ALL DATA - NON-RECOVERABLE
Turn on the computer and repeatedly press the F11 key, about once every second,
until the Choose an option screen is displayed, and then continue.

On the Choose an Option screen, click Troubleshoot, and work your way through the screens.

Second Part:-
This may require another PC. Find and Download your .iso from…

https://www.microsoft.com/en-us/software-download/windows10
Expand/Extract/Burn the iso Image onto a DVD/USB as needed.
Microsoft’s Creator Tool will make the required DVD or USB.

Even though it has NO actual HP software/drivers included, you may be able to
XCOPY the C:\Users\* area onto a ‘large’ USB stick, via the Command Prompt.

You’ll need to try various drive letters; D:..-..Z: until it’s matched - could be G; mine’s S:

C:\>XCOPY C:\Users\* S:\ /e /i /h (then files like those 3 listed below get copied over)

C:\Users\desktop.ini
C:\Users\All Users\agent.1509128044.bdinstall.bin
C:\Users\All Users\HP Deskjet 2540 series\Help\flash\zoom.swf

Then you can try System Recovery Options / Advanced Options shown in the screenshots.


NB: - W10 Begin with the Automatic Repair, then Startup Settings etc.

From either the C:\ or the X:\ prompt try the following

cd boot
bootrec /FixMBR
bootrec /FixBoot
bootrec /RebuildBCD

If in doubt please ask.

You kind of asked me at the end of your post. I have tested the hard drive and it has passed multiple times. I have also reset the bios from the HP website. Date and time are held from what I could see, it still shows the correct time and date for my time zone. I have tried to hard reset multiple times and nothing worked, even tried the F11 to do a factory reset and it won’t work either. I did save most of my important documents on a external hard drive thankfully. I can try to find the ISO online and download it onto a USB drive, but like I said, not that technically savvy. Going to try to get it repaired to geek squad but due to the virus I can’t. If anyone else has some more insight that would be great! Thank you.
