Hi, 

I was doing a system restore which took forever and never completed. So I forced a shutdown by long pressing the power button. Since then, if I try to switch it on, it gives me a "preparing auto repair" and later shows a "Your PC ran into a problem and needs to restart. We're just collecting some error info., and then we'll restart for you".  This appears and then it immediately goes back to the preparing auto repair screen and goes on and on without completing booting. Please help me out. ThanksFirst thing i see on the screen when i try to bootNext thing that appears after the preparing auto repair screen. Then this immediately goes back to preparing auto repairtest resulttest result

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 Sir for your prompt response. However my notebook battery is in-built and irremovable. Unless I would have to unscrew the base to access the battery

Hi

I stole those instructions from a HP page, and usually the IF you have a battery, remove it, keyword IF is overlooked. If there is no 'battery door' then you don't, and it is valid with desktop.

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
