[SOLVED] Can't Boot Into BIOS Because the System Boots Up Too Fast

No matter how much i spam F2 on startup, it will always log into windows. I've already tried the method of going into recovery settings to restart via. UEFI, but when the system restarts it doesn't boot into BIOS and just boots into Windows. Anything else I could try? I've attempted to unplug the SSD and boot, but the computer doesn't even boot when I do that. My Motherboard is an ASUS B350-F and I gotta get into BIOS as my ram is severely underclocked (2133mhz from the stock 2666mhz)

Go to control panel > hardware and sound > power options > click "choose what the power button does," on the left side. > click "change settings that are currently unavailable" above the power button and lid settings. > in the bottom category under "Shutdown settings," deselect "turn on fast startup." > click "save changes." Fast startup does what its title implies, it boots up the computer faster.

have you tried spamming F2 after a restart? Restarts are generally the only time your PC is actually off (if you have fast startup turned off). If you have an ssd, you don't really benefit from it - turning it off might make F2 react on any startup - https://www.tenforums.com/tutorials/4189-turn-off-fast-startup-windows-10-a.html

actually, it does more than speed up startup but it can get in way of bios

Is it this motherboard? ASUS ROG STRIX B350-F - if so, here is manual - https://dlcdnets.asus.com/pub/ASUS/mb/SocketAM4/STRIX_B350-F_GAMING/E13031_ROG_STRIX_B350-F_GAMING_UM_V2_web_20170606.pdf

why do you want to get into BIOS?

I just turned off Fast Startup. I shutdown the computer and booted it back up while spamming F2 but it still booted up into Windows. This still happened when I did a restart instead. I want to get into BIOS because my RAM is very underclocked. It's currently at 1000mhz or 2133mhz (forgot which) and I gotta get into BIOS to fix it.

I've tried to reset the CMOS. I shorted the two pins for 10 seconds, and started the PC while holding in the Del key as in the manual. Still just booted me into Windows. Second time i took out the Battery, shorted the pins and put the battery back in and started while holding in Del key. Still just boots into Windows.

If there was another way to get into BIOS besides resetting CMOS and pressing buttons, I would suggest it instead.

I can ask for a 2nd opinion, it seems to me ifts the only way into BIOS now. 9 out of 10 times resetting CMOS is enough to get you in,

Just checked on CPU-Z for my memory clock (which doesn't require BIOS) and it says that the DRAM clock is 1064mhz, should be higher as I have 2x4 ddr4 2666mhz sticks. Can't change the freq though because I can't access BIOS. Afraid this may impact my performance a lot as I'm running a Ryzen CPU.

Did you go into Control Panel, Power Options, Choose what the power button does link, Change settings that are currently unavailable link, then uncheck Fast Startup and OK your way out before trying the advanced restart options?

The only reasons I can possibly think of for the behavior you videoed is that Fast Startup is on and taking precedence, or there is some other corruption in your current Windows 10 installation that is preventing the advanced startup from working as it typically does.

If Fast Startup is definitely off, then give the following a try:

Using SFC (System File Checker) and DISM (Deployment Imaging Servicing and Management) to Repair Windows 8 & 10

If that doesn't work, then try a full repair install of Windows 10 following one of these three instruction sets of your choosing:

Non-Destructive Repair of Windows 10 - Answers to commonly asked questions

Doing an In-place "Upgrade" to Reinstall Windows 10 Keeping Apps/Programs and User Files

How to: Perform a Repair Upgrade Using the Windows 10 ISO file

And if the above doesn't solve it call Asus support.

Well, I've ran both of those commands, it said that the corrupted files were successfully repaired. However, when I restarted the system into UEFI through the recovery method, it still just booted into Windows. I've called an IT Specialist in my area and hopefully he will be able to fix it for me.

Unplug the power supply from the wall. Remove the CMOS battery for five minutes. Press the power button for 30 seconds, continuously, during that five minutes. Reinstall the CMOS battery. Plug back into the wall. Power on. Spam the F2 or Delete keys.

If that doesn't work, disconnect ALL storage devices and THEN reset the BIOS as outlined above.

If you cannot power on the machine, pass the POST process and get into the BIOS after doing that, then there is something wrong with your motherboard.

Also, I think you are confusing the terms "boot", which means to load the operating system and get to a point where software and applications can be run, and simply powering on and passing the POST test routine which would allow you to enter the BIOS and make changes. No system can "boot" without a storage device containing the operating system attached, but they CAN power on, POST and allow BIOS access, so long as nothing is wrong and so long as we are talking about the Windows or some flavor of Linux OS when we say "boot".

Well, I just did that now and the pc powers on but nothing shows up on screen

What are your full system specs including graphics card model, CPU, etc.?

Honestly, I'd contact ASUS. If you've reset the BIOS, it should NOT be on Fast or Super fast boot settings anymore, and you should easily be able to access BIOS. Also, no display indicates either a lack of pre-windows support for the graphics card or integrated graphics (Maybe, on CPU models not supported by current BIOS version that HAVE iGPU?) or something out of the ordinary.

When I booted up the pc for the first time, it showed bios and everything, but after that I couldn't access the bios. My specs are a Ryzen 3 1200, Asus Strix b350f, 8gb ddr4 2666, Asus Strix Rx 570 4gb
