How do i access BIOS without UEFI?

[DanielFromSteamYouKnow]

I recently built a new PC and accidently installed a 32-bit Windows 10 version instead of a 64-bit (which is supported by my system). But i think i selected fast boot on my BIOS at first startup and therefor i can't access my BIOS because my keyboard doesn't get powered until Windows 10 is already booted up (However i do see the MSI screen pop up asking me to press F11 for boot setup and DEL for main BIOS, but very fast). So i want to reinstall Windows 10 from a USB device (which i already made with the media creation tool) but i can't boot from my USB because i can't access my BIOS. When i try to do an advanced start up from Windows it doesn't give me the UEFI firmware settings and the Boot from USB or DVD option. I seriously see no way to enter my BIOS 🙁((((

Remove the CMOS battery or set the jumper to clear your bios
You should be able to access it then

Most systems you dont even need to do the jumper. Just remove the CMOS battery and let it sit for a few minutes and also try to hit the power button with the power cables disconnected to drain any remaining power from the system.

Is it possible to short it with just a piece of conductive material or does a short that usually comes with motherboards have some sort of mechanism that lowers the voltage

Do you mean let it sit for a few minutes with the power on or just take it out with no power and then put it back on later?

Power down the system
Unplug the power cables
Remove the CMOS battery
Press the power button a few times to drain remaining power out of the systems PSU
Let sit for 2-5 minutes
Plug CMOS back in
Plug power cables back in
Turn on system

BIOS should have reverted back to defaults.
