How do I activate Advanced Bios mode on my laptop?

[SvyatoslavSomov]

Hello, there is no Advanced Bios subsection in the Bios of my HP PAVILION 17-ab430ur laptop. According to tips from the Internet, I tried to activate it by simultaneously pressing A + F10 when pressing Esc during startup. But the Bios just opens and the advanced Bios sub-item doesn't appear! Help me activate it!

Sorry, but accessing Advaned BIOS option on HP PCs is not possible.

OEMs lock out the advanced BIOS options to prevent customers from making changes to options that can destabilize or otherwise damage the PC -- and then send it back for repair under warranty claiming they did nothing to it.

I know only SOME of the advanced options are risky, but it's simpler to disable access to ALL advanced options than to allow/disallow on an individual option basis.

That's the course of action that HP has chosen.

And yet, at least 1 option for activation is there? I don't think I can put Windows 7 without this menu.

IF you're switching a PC that came with Win10 to Win7, you are going to be faced with two serious issues.

First, HP does not supply Win7 drivers for the newer Win10 PCs, and without those drivers, since laptops use specialized hardware, one or more hardware functions are not going to work properly.

Second, the Win10 license does NOT include downgrade rights to Win7 -- so you will have to purchase your own Win7 license, and you provide that product key as part of installing Win7.  You can skip that, and install without activating, but Win7 will then expire unless you provide the key within 30 days of installation.

У меня даже установка Windows 7 не начинается! Сразу вылетает с ошибкой если Legacy support в Bios выбран, а если в UEFI, то просто зависает загрузка.

By the way, hello from Khabarovsk:) This Is The Russian Far East)

I don't even start installing Windows 7! Immediately crashes with an error if Legacy support is selected in the Bios, and if in UEFI, the download simply freezes.
