Solve : Cannot access the BIOS on a laptop?

1.	Solve : Cannot access the BIOS on a laptop?
Answer» I apologise in advance if this is in the wrong forum (in which case, mods please feel free to move it), but I think the following problem is probably best suited to this forum. A friend has passed me his laptop (an ASUS K52F, running Windows 10) to sort out, as it was running slow (the usual problems, malware, unwanted programs etc). I couldn't use any boot keys to get into the factory restore, so I used Windows itself (via holding down SHIFT when clicking on RESET on the Windows shutdown menu) to get me to the factory reset menu, and the factory reset worked as it should, and now the laptop is running great. But the thing is, I want to know how to ACCESS the BIOS and the boot menu (so I can make the laptop boot from a USB stick, DVD-drive, etc). I don't need to know, as the laptop is working now, but I'm curious and I'll probably need to know it for sometime in the future. You can't always rely on Windows running when you need to accessFactory reset, so working boot keys are a must. But the problem is, no matter what keys I press when I turn on the laptop, I can't get into the BIOS or the Boot Device Menu. According to: https://kb.wisc.edu/page.php?id=58779 the boot keys for the laptop (ASUS K52F) are F8 for the boot menu (seems strange, but I've found other sites via Google that confirm the laptop uses the same key as Windows boot) and DEL for the BIOS, but whether I hold down one of these keys, or keep TAPPING on it when the laptop starts up, then it's as though no key is held down, and Windows 10 boots up. So of course I can't boot from a USB stick or DVD drive. I've tried the other usual suspect too (Esc, F9, F9 + FN, F11, F2 F1, etc) with the same result; Windows just acts like no key has been pressed/held down, and boots up to the Windows desktop. Is it possible that somehow some settings in Windows 10 can cause the boot keys to not work? I wouldn't have though so, as I'd think the BIOS related code (which runs before Windows even starts, surely?) is never altered by Windows. Or is there something else I'm missing? Thanks for any answers.Windows would not effect anything at boot because it hasn't loaded yet.

It turns out that the problem was Windows Fast Startup (https://www.howtogeek.com/243901/the-pros-and-cons-of-windows-10s-fast-startup-mode/), which if you'd not heard of (I hadn't) then you should probably look at that site, it explains how when using Fast Startup, the boot keys are ignored. I've disabled Fast Startup, and now using ESC now allows me to choose what device to boot from, and using F2 enters the BIOS, but F8 is still ignored. But I know that Windows 10 has issues responding to F8, so it's not caused by Fast Startup.

As you say, it is fast start-up. It's in "Choose what the power buttons do" and you may have to click "Change settings that are currently unavailable". 2 things I found with my Dell laptop: 1. If fast start-up is enabled, it won't respond to Wake-On-Lan signals. 2. I am using Windows 10 Insider builds, and if I disable fast start-up, every NEW build re-enables it and I have to GO in and disable it again.
