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).

So if the hardware passes, then it is attempt a software fix.

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.

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

Thank you for this information. I am in this situation from doing a f11 factory reset. During the process computer turned off or possibly battery went dead I came back in few minutes later after it had already started to find this.

It has been a nightmare since that point, I tried to recover using iso image that was 32 not 64 then when I got the 64 putting it onto a 32gb USB some files were too large. Seems everything has worked against me. The other computer I have is a 16gb with not enough space on the windows 10 c: drive to save it. I tried from my galaxy s20 ultra then couldn't format to anything else. Il try the power button idea I only did a 15 sec not a 4 then 15 so maybe. It wouldn't let me into f11 anymore but I've tried legacy mode then disabled it tried few things that just seemed to make things worse

Oh and smart hard disk test and extension test both passed fine. Memory test passed.
