Flashing boot block

[PiR_Legrand]

Hello

I had a problem with my fan so I followed the HP guide and I arrived at the step of the update of the boot

Everything was fine but after the auto reboot the computer was stick with a message flashing boot block 86%

It is stuck like this for more than a day

Can you please help me?

Hi

Hard Reset?  https://support.hp.com/us-en/document/c01684768/

Turn off the notebook.
Plug the notebook into a power source using the power adapter.
With the notebook off, press and hold the Windows logo key and the B key at the same time (WinKey +B).

NB: On some notebook models, it might be necessary to press and hold the Windows logo key and the V key (WinKey +V).

While pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows logo key and the B or V key until the HP BIOS update screen displays or you hear a beeping sound (usually 8 beeps).

If in doubt please ask.
