No boot device message

[Gray5555]

HPPavilion 595-p0074 i5-8400 with 128gb M2 ssd and 1Tb hard drive, 12gb Ram, Windows 10 OS. Experienced a few freezes then one day it would not load the OS, got No boot device message, please install an OS. Ran tests, quick and long, memory and drive 1, both passed. Seems like the SSD died?? What is my next step, buy a new SSD and then how do I reinstall other programs and  Windows? Also, will the  Recovery partition be on the 1Tb disc drive?  I do not have another computer to download anything unless it can be done on an old Windows Lumia 950 phone.

Typically the 128GB M.2 drive was used to hold Windows and the 1TB drive was for data.  If you did not instruct Windows to use the data drive for storage, then most likely there is very little on that drive.  The OS would have been on the SSD and there are choices that can be made.  The 128 GB PCIe NVMe M.2 Solid State Drive can be replaced.  I would purchase a larger drive as they are relatively inexpensive.  1TB is probably going to cost less than $100.00 in the US  IE:

Or you could even use the 1TB data drive and load Windows 10 on there.- just slower performance.

For the software - that model was supported in the HP Cloud Recovery Tool

But it requires a functioning PC to download the software.  Microsoft also provides the Windows 10 software

If you need the install media for Windows 10, you can make it from this Microsoft download

https://www.microsoft.com/en-us/software-download/windows10

With a working PC, scroll down to the "Using the tool to create installation media"
and then follow the directions. You can make either the DVD or USB. Use this new media to install Windows 10.
When the install asks for the product key, click the "I don't have a product key" option to continue,
then the install will continue. It will be activated once it connects to the internet, as it uses a digital key.

Any other software and data that was saved on the failed SSD drive is probably gone.  I have not actually tried to recovery anything from a failed SSD but old failed regular hard drives will sometimes give back some data.  If you saved anything on the data drive or installed some software on there, it will still be there.

If you like the PC and wish to revive it, I would replace the SSD with a new drive and reinstall windows 10 using one of the two methods I described.  You can ask a friend to make the downloads for you or go to the public library to make the USB flash drive of either download.  Use a 32GB flash drive.

Thanks for the detailed reply. I went out and bought a WD Black NVME 1Tb M2 ssd to replace the original 128gb m2 ssd. Installed it after removing the original, no apparent problems with the installation. However now I get less from my PC than before, meaning I can get to the blue screen that gives F choices, but none of them work, or my keyboard isn't working, i did have to disconnect the keyboard when i replaced the ssd. IDK.  I get the same message as before if I turn on the computer without pressing any keys. Boot device not found. Please install OS. Hard disk 3F0---. I got a usb drive and downloaded the boot file from Microsoft , think I did that correctly. I tried starting the pc with the usb drive in the slot and not, no difference. Before installing the new ssd I think I was able to change the boot device option to usb hard drive but not sure it actually changed. But now I can't get back to boot options to check. So one thought, could it be the hdd that died??. But then this computer always loaded the os very quickly, like 15 seconds, so that should mean the os was on the m2 ssd, correct? I'm stumped

If you are getting to the blue screen with the F choices and pressing an F key does not do anything, it might be the keyboard is not working.  The spec page indicates a wireless keyboard, which might not be detected or the USB port does not recognize it.

Make sure it is in a USB 2.0 port, as sometimes the USB 3.0 ports do not work at boot-up, until Windows starts.

With the Microsoft download on the USB flash drive and in a USB 2.0 port, try this.  Start tapping the Esc key BEFORE starting the PC and then press the start button.  Keep tapping the Esc key until a popup menu shows. Then pick F9 from that menu and then choose the USB boot choice and then enter.

If the pop-up menu does not appear, then you might need to use a USB keyboard that is not wireless, just for these steps.

FYI: I always have one laying around, just in case.  You could borrow one or get an inexpensive one, - $10.

Ok, hooked up a known good usb wired microsoft keyboard, no change. Seems like the only function that works is the ESC key to get to the blue start up screen,  and the Enter key which only brings up the boot device not found screen from the blue start up screen.

. Tried pushing the esc key before, during and after hitting the power button, all repeatedly, continuously. The blue start up menu appears but none of the function keys work. I've tried it at least two dozen times with slight variations to see if that made a difference, nope.  Nothing different with the usb drive inserted or not, so could that Microsoft file not be correct ?? Or, I read where someone had to add an HP file to reload Windows if I read that correctly?? 

After replacing the M2ssd I still get the hard disk error message, 3F0, so does that mean the hdd is also defective or maybe it's not recognized, or could the motherboard be defective or?? IDK

Also decided to replace the motherboard CR 2032 battery as it was five years old. Measured 2.75v so it was time. No change in any of the issues discussed above however.

This is a puzzle.  The message about "No Boot Device" means that the system could not find the instructions to send the BIOS to where Windows is installed. 

What I typically would try is to disconnect the other hard drive.  Then I would use a Linux distro (typically Ubuntu or Mint) that is on USB , Or you can make the DVD version, since you have a DVD drive, also.

The Live version will act as the OS and will tell you , once it is loaded, if the hardware is working OK.  It will also be able to determine if the SSD is OK.  You could then have the old SSD in place after making sure the PC will boot to the new media which has the Ubuntu on it and check out the SSD.  There is a possibility to scan the old SSD with another computer to what is up, if this stubborn PC will not boot into Ubuntu, either.

Other than trying that, I am at a loss.
