Also for the little history, the screen of my laptops il almost dead so i would like to transform it in a pc desktop. But for this i need to modify the bios for always boot on the external screen, but i can't acces to the advanced settings, because hp is evil, and i have already try everything on internet to have acces to it and this is my ultimate solution to serch some help
I know that a russian succed to reach to the advanced settings with the same pc but on the InsydeH20 F.04 that i can't install because the version are "incompatible" but this is the same pc so i don't really understand why

Thanks you you so much for your quick answer !  
I just make the manipulations and it work i have F .04 now !

But even when i press fn+tab 3 times at the same time and save and reboot nothing happens...
I have try this multiple time but still nothing happens. I have also try A+F10 for go in   bios but same result i still don't have advanced option... 
I feel a bit stupide also your answer was in the description section of the video i have sent but i don't read russian .
Anyway thanks you a lot

i still don't have advanced option...  :(

It is very tricky to hit a key in time. If you can't do it with one press, try pressing "A" quickly several times throughout the entire power-on stage.

I use a clamp to have a good precision when pressing fn+tab à the same time ? Is there precise time to wait between every push of fn+tab at the same time ?
I didn't get the "try pressing "A" quickly several times throughout the entire power-on stage. "
I have press A several time quickly and pressing F10 for go in bios and still nothing appens, am i doing something wrong ?
