Microsoft Windows 10 (32-bit)

We are unable to start up the PC, always stuck at the screen showing " Diagnosing your PC " After several hours it will show a screen indicating " Advance option " 

Clicking it will arrive at "choose an options page" with the following option :

1) Continue - exit and continue to Window 8.1  ( doesn't work, go back to ' Diagnosing your PC " screen all over again )

2) Turn off the computer ( when turning on the same issue ) 

3)Use a device - recovery DVD ( don't have this product )

4) Troubleshoot - not clickable


Hope someone can be so kind to advise how we could proceed from here.

Thank You

3) Use a device - recovery DVD ( don't have this product )


See: Download Windows 8.1 Disc Image (ISO File) (microsoft.com)


to get a copy.


4) Troubleshoot - not clickable


That is unusual.  It should be "clickable", if the computer still contains the original disk-drive, i.e., not something that you have replaced/upgraded.


Note that you could download Windows 10, and install it, preferably onto a brand-new disk-drive.

Keep your current disk-drive, and connect it as a "secondary" disk-drive, to copy all your Personal Files from "old" to "new".

Welcome to the HP Support Community! I'd like to help!


I see you are experiencing issues with the HP Envy PC not booting to windows just stuck at diagnosing pc. 


The BIOS can be corrupted during normal operation from a failed BIOS upgrade, or damage from a virus.   


Recover the BIOS using a key press combination. 


Turn off the computer. Press and hold the Windows + b keys, and continue to press those keys while you press and hold the power button for 2 to 3 seconds. Release the power button, but continue pressing the Windows + b keys. 


The power light remains on, and the screen remains blank for about 40 seconds before anything is displayed. You might hear a series of beeps (usually 8 beeps). Eventually, an HP BIOS Update screen is displayed and the BIOS update begins automatically.   


NOTE: If the HP BIOS Update screen is not displayed, press and release the power button, and then immediately press the Windows + b keys at the same time, repeatedly, until the computer beeps or opens the HP BIOS Update screen. 


After the BIOS is recovered, a Continue Startup button is displayed and a timer counts down. Click the Continue Startup button to restart the computer immediately, or wait for the computer to restart automatically when the timer reaches zero.


If issue still persist then test the hard drive using HP PC Hardware Diagnostics UEFI to rule out other hard drive issues

  1. Start or restart the computer.
  2. Press F2 repeatedly during start up to enter the HP PC Hardware Diagnostics UEFI utility.
  3. Select Component Tests > Hard Drive > Quick Test.
  4. Click Run Once.

Once the test completes, results are displayed on the screen.


If the drive passes all tests, continue to restore a computer back to the factory default, which will isolate whether it’s a software or hardware issue. 


The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system. 


Click here for the HP Cloud Recovery Tool (Windows 10) link.


For any hardware issue or repair please click on the link Phone Assist Worldwide 


Hope this helps! Keep me posted.
