Cannot use F5 F6 in the BIOS

Hello, my laptop no longer reads the internal hard drive. So I’m trying to boot from an external hard drive, but once in the BIOS the F5, F6, F9 and F10 keys don’t work. I can see my hard drive, but I can’t put it in the first position, and apparently that’s essential. Thanks in advance for your future answers.

    my keyboard works fine except for the famous f5 f6 f9 and f10, the rest works: for me, it doesn’t really work!
    Try borrowing a USB keyboard to see if it does the same.

    Hello...
    First try to connect an external USB keyboard..
    Can you not use + or - in the bios or the arrow keys?
    Regards,

    I tried with the Fn key, but that doesn’t work either. And the whole keyboard is functioning correctly; moreover, I don’t have an USB keyboard :/

    My arrow keys work fine; I can navigate in the BIOS, I can also use Enter and F1. There are really only F5, F6, F9, and F10 that don’t work, and + and - don’t do anything in my BIOS, so that doesn’t work either.

    When you’re in the BIOS, it should show you all the available commands on each screen... you definitely need F5 and F6 to move up and down on THIS screen, right?
    Because for F9 and F10, you probably need Escape to return to the tab bar, but not all BIOSes are the same...
    Otherwise, blasting F9 or F10... from power-on, don't you have the "boot menu"?

    Yes, it is indeed marked F5 and F6 to change the boot order. I can press F12 at startup to have a sort of boot menu where the different boots (CD, my external hard drive, and the internal one) are displayed, but when I try to boot from my external HDD it doesn’t work.

    Do you mean that, in whatever menu you’re in, your keyboard isn’t working?
    Is it USB or PS/2
    Try a PS/2 if you have the jack and the keyboard...

    It’s a laptop, so there’s no USB keyboard (I don’t have one) and my keyboard works fine except for the famous F5, F6, F9, and F10; the rest work!

    Have you tried with an external keyboard?

    I confirm: the F5 and F6 keys work with an external USB keyboard, whereas they didn’t work on the laptop.
    Thanks for the tip. It was something you needed to know!
