Hi

Not really (you would need a friend/family/college etc to make the USB).....

So it is only the second part that applies?

The First Part only works when a valid Recovery Partition is enabled.

If you get an error message, AND/OR have DATA you wish to try and save

(using the XCOPY command) then move onto the Second Part, to create

your own Repair/Recovery/Rebuild/Re-Install media or buy one from HP.

First Part:-

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/windows8ISO

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

This 3rd party site does not need a Licence Key to download…

heidoc.net/joomla/technology-science/microsoft/67-microsoft-windows-iso-download-tool

Expand/Extract/Burn the iso Image onto a DVD/USB as needed.

Microsoft’s Creator Tool will make the required DVD/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 / 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
