My hp elitebook 810 G1 does’nt recognize any operating system on the hardrive After i’ve check all the boot option settings in the bios.
Could you please advise me or assist with any solution?
Thanks.

Hi

Is this because it has passed all the Diagnostic tests and wont boot?

Is it generating any error codes?

Are there any spinning circles, fixed logo's or similar?

Please 1st try a Hard Reset

Press and Hold the PWR off button for 4 seconds to force a PWR off.

Unplug from the wall.

If you see a battery compartment door, your computer has a removable battery.

Remove any removable battery.

This is valid for most notebooks;

Press and hold the power button for 15 seconds to complete the reset.

Re-insert any battery you removed.

Thank you for the quick response but unfortunately any of the solution mentionned above worked. It has passed the hardrive test, and no error message is appearing on the screen.
Thank you!

Hi

So now....

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…
(You will need a NON_OEM key for W7);
W8.x and W10 should activate automagically from their embedded licence key.
https://www.microsoft.com/en-us/software-download/windows7
https://www.microsoft.com/en-us/software-download/windows8
https://www.microsoft.com/en-us/software-download/windows10

For when it’s a NON MS OS ( iOS / Linux ) creating the install media.
www.microsoft.com/en-us/software-download/windows10ISO

A 3rd party site is (Please be careful)...
https://mirror.corenoc.de/digitalrivercontent.net/

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:- W7 Try running a Startup Repair more than once for a full fix.
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 the above FAILS then please try:-
