Can't get into BIOS on my MSI board

on msi it's Delete for the bios and F11 for the boot menu. tap it over and over from the moment you hit power, holding it down doesn't always register. also check where the monitor is plugged in. if you've got a graphics card, the screen needs to be on the card's ports, not the motherboard ones, or you won't see anything until windows has loaded. if nothing works at all, clearing the cmos (pc unplugged, pull the coin battery for a few minutes) puts fast boot back to default along with everything else.

Fast boot will do exactly that. Way round it from inside Windows: Settings > System > Recovery, Advanced startup > Restart now, then Troubleshoot > Advanced options > UEFI Firmware Settings. It reboots straight into the BIOS. Once you're in, turn off MSI Fast Boot if you want Delete to work again. Also worth checking you're not on a wireless keyboard, some don't wake up early enough to register.
