PC won't restart after update

[PragueImp]

I updated the drivers on my PC about an hour ago. It installed them, restarted, bleeped loudly 5 or 6 times and now is doing nothing! Help please!

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

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

AND/OR - Windows Logo key + Ctrl + Shift + B
(This key sequence actually restarts you graphics driver (W10 only).)

AND/OR - If you’re using multiple displays, try projecting video to a different monitor.
Press the Windows Logo key + P, select a display, and then press Enter.

Turn off the computer, and then connect the power cord.
Press and hold the Windows key and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.
Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.
The HP BIOS Update screen displays and the recovery begins automatically. Follow any on-screen prompts to continue the startup to complete the recovery.
HP BIOS Update recovery in progress

If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next step to install a BIOS recovery file from the HP website.
If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the button for only 2 to 3 seconds.

Thanks for the detailled reply.

Unfortunately it is a bit late - after trying a lot of similar things I took it to a repair centre yesterday!

Hopefully they know as much as you do!

Prego.

Next i may well have suggested....

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

If the above FAILS then please try:-

http://www.thewindowsclub.com/install-windows-10-from-usb

Who knows what i would suggest after the above.
