ProBook 4740s Black screen on Windows startup Windows 10 Anniversary

ProBook 4740s
Microsoft Windows 10 (64-bit)

Hi 

 

My PC goes to a black screen after the Windows logo and the rotating dots under the Windows logo does nor appear.

With a long process I can get windows to start in safe mode.

I did all the scans and found no harware issues.

I also downloaded and installed all the latest drivers from the HP web site and still no luck.

Any advice to solve this?

PC works fine in Widows safe mode only audio does not work in safe mode.

 

Thanks

Hello,

 

Thank you for posting in the HP Support forum. Welcome!

 

How about resetting the Windows 10 ?  You can perform some kind of repair by using the Reset option with keep your files in.

 

1. Click on Start > open Settings, and click/tap on the Update & recovery icon.
2. Click/tap on Recovery on the left side, and click/tap on the Get started button on the right side under Reset this PC. (see screenshot below)

 
This will open the C:\Windows\System32\systemreset.exe file.
 
Choose the option to keep files and continue. Details >> http://www.tenforums.com/tutorials/4130-reset-windows-10-a.html
 
Under certain curcumstances you might be asked for Windows 10 installation media. Should you encounter issues, let me know and I'll provide advice.

ProBook 4740s Black screen on Windows startup Windows 10 Anniversary

Hi

 

Thanks for your reply, I have tried the reset option before and it did not work. I tried it again now from the settings menu after startup in safe mode and it also did not work. I used the reset to keep personal files.

I upgrade the PC from Windows 7 to Windows 10 in July 2016 and on 30 August I upgraded to Windows 10 Anniversary. I was short on hard disk space and chose to delete the old windows installation files. Seems like I had too much trust in Windows 10.

Any other suggestions?

 

Thanks

You Are Most Welcome :)

 

Thousands of people worldwide use Win 10 but yes, I feel for you when you say you had too much trust of it - I am not big fan of it, though.

 

Anyway, If you can now boot into Safe Mode, please, create a back-up of all your data.

 

Since you previously performed upgrade from Win 7 to Win 10 on this very same computer and if you used Win 10 for a while and if Windows 10 was activated (it's licence was activated), then your computer has a Digital entitlement option stored on Microsoft servers. Because of this, you no longer need a code/lic key to activate Windows if you need to reinstall it.  More info:

>> http://www.winbeta.org/news/digital-entitlement-a-new-method-of-activation-in-windows-10

 

You can directly download Windows 10 ISO from MS site or download Media creation tool from Microsoft site, create installation DVD or installation USB  and  proceed with clean installation/reinstallation.

 

>> https://www.microsoft.com/en-us/software-download/windows10ISO

 

 

 

How to create bootable ISO on USB device >> http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows

or

How to write ISO to DVD >> http://www.ubuntu.com/download/desktop/burn-a-dvd-on-windows

 

 

 

When ready with the USB drive or with the DVD:

 

* Ensure Secure Boot is disabled.

* Ensure Legacy mode is enabled.

* Save the UEFI/BIOS changes.

Details>> http://support.hp.com/us-en/document/c03653226

 

Eventually, please, shutdown the computer using the power button.

Insert the Windows USB thumdrive or the DVD prepared previously

Power  on the PC.

As soon as you press the power-on button, keep hitting the Esc button (like tap-tap-tap).

This should open a HP Startup Menu which may look similar to this one

 

Choose F9 to open Boot options. Select the thumb drive as boot option.

 

Follow the on-screen instructions to install Windows 10

Install drivers taken from HP web site when Win installation completes or via Windows Update/Device Manager >> http://support.hp.com/us-en/document/c03330139

 

 

 

Hope this helps. Let me know how it goes. Smiley Happy

Hey Jacob8,  In safe mode try and uninstall all programs and then go to device manager and see if there is any exclamation marks or driver conflicts, uninstall or disable all conflictiong devices and then restart PC normally. 

 

 

You can also try rolling pc back to previous build as anniversart update has known freezing issues.

 

Using the Settings app from Safe Mode

1.      Restart your PC. When you get to the sign-in screen, hold the Shift key down while you select Power > Restart.
2.      After your PC restarts to the Choose an option screen, select Troubleshoot > Advanced options > Startup Settings > Restart.
3.      After your PC restarts, you'll see a list of options. Select 4 or F4 to start your PC in Safe Mode.
4.      Open the Settings app.
5.      Select Update & security and then the Recovery tab.
Under “Go back to an earlier build”, click the Get started button and follow the instructions.

 

Please click “Accept as Solution ” if you feel my post solved your issue, it will help others find the solution.
Click the “Kudos, Thumbs Up" on the bottom left to say “Thanks” for helping.
