HP Pavillion Won't Boot Even to BIOS

[Mohamed-Elnahla]

my laptop was working normally but along the previous days Microsoft Windows 10 was trying to download and install an automatic Update (As i remember it was called  HP Advanced Configuration and Power Interface)

that update failed a lot and i don't know if that update was installed sucessfully or not

but yesterday i tried to change my boot options to legacy support then i pressed F10 to save that

laptop reboot after that and stuck on black screen with white word (Press esc key for startup menu)

whatever the key (F10 or F11 or F9 or F2 or esc) i press it keeps saying that it will boot it but it stucks on that 

So now i can't even boot to BIOS or any Startup things 

some fixes i tried :

- press win key with B on boot to boot BIOS recovery (that only makes my CAPS LED blinked 2)

- use usb to make BIOS recovery (same result that only makes my CAPS LED blinked 2)

- Unplug the battery then power laptop using AC only

(I NEED ANY URGENT HELP PLEASE)

Hi

"yesterday i tried to change my boot options to legacy support"

If you have a Secure Boot / GPT formatted HDD and then select Legacy Boot the machine will quite often report No Bootable Device  found.

WinKey + B looks to take a backup copy from the HDD and use that, you dont have a working HDD.

So try and return to the previous state and ask again, also what is the long term aim for using Legacy boot?

You will need a blank 32GB USB flash drive and another PC for this.

Download the available BIOS softpaq. 

Plug the USB flash drive into a USB port. 

Double click on the BIOS softpaq.

You will see the available options.

One option is to create a recovery USB Flash drive to use on devices with a corrupted BIOS.

That would be your device.

Create the USB Flash drive.

When that is completed, it can be used to restore the BIOS on your notebook. 

 Watch the following video to learn how to recover the BIOS. This time do not select legacy support. Leave everything in the default settings except for the date\time settings. 🙂

Thanks for reply but:
- i have no access to BIOS to change settings Back
- using Win+B makes screen black and caps led 2
- i was trying to use legacy to boot OS installer (was going to install another OS beside my Windows)

Hi

So not even powering on with the ESC key already pressed will give you access to the BIOS?

So the next step is to hold down the WinKey + B and apply power for 3 seconds and release the WinKey + B after 10 seconds to boot from the Flash Drive as Erico has rightly pointed out.

I tried that before and i made a recovery USB and tried to boot from it using Win+B and pressing power for 3 seconds
But as i said before that doesn't make anything only makes CAPS LED 2

Hi

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.

Then

Caps Lock/Num Lock LED     Component Tested     Error Condition
LEDs blink 1 time     CPU     CPU not functional
LEDs blink 2 times     BIOS     BIOS corruption failure
LEDs blink 3 times     Memory     Module error not functional
LEDs blink 4 times     Graphics     Graphics controller not functional
LEDs blink 5 times     System board     General system board failure
LEDs blink 6 times     BIOS     BIOS authentication failure

Linux, al least any decent one, will use Secure Boot.
