I don't know if its a bug or this is how windows 11 is, I just can't access my bios nor the advanced startup, if I boot the computer and spam the BIOS MODE (delete key) it just goes into a black screen and nothing happens it just stays black as long as I keep it running same thing happens with trying to go into advanced startup after it restarts same thing happens black screen and nothing else no cursor nothing even the monitor goes into power saving mode.
I checked everything from cables to bios updates and nothing
plus it was completely working on windows 10 I can go to advanced startup no problem BIOS no problem
after updating to windows 11 it just doesn't work at all.
also a note that when I boot the computer or press the power button it stays black for 3-5 seconds and then instantly loads windows I don't see the motherboard logo or the modes I can go to before it starts loading windows.

although it seems the solution is different depending on your system but for me switching the hdmi cable from being connected to my gpu to the motherboard allowed me to actually get the splash screen when you boot up the pc to actually get into the bios
PROBLEM SOLVED
Hi guys!
Long short story. I finally bought my own machine, which, because I am a geek, I assembled myself. OC is not an obstacle for me, so after the entire installation and after several unsuccessful attempts to enter the BIOS, I started to wonder why I spent so much money on equipment that I cannot configure myself.
However, after a long and tedious reading of all your posts regarding refreshing, fast boot, etc., I found the reason!
Well, in my case, having an Nvidia card and a Samsung monitor with 240 Hz refresh rate, it helped... changing the version of the DisplayPort connector! In order for me to use G-Sync, I must have the connector set to class 1.4. Changing to class 1.2 solves the problem!
However, what surprises me is that I tried to connect my different monitors using various methods, but it didn't work every time. Resetting the CMOS when removing the battery from the motherboard helped temporarily.
To sum up, thanks for the guidance and I hope my solution can be useful to someone!
Interesting because I just posted going from 2.0 to 1.4 and it worked. Therefore it doesn't seem to be dependent on DP version, but rather just a change? I also have Nvidia G Sync fwiw
I've been having same issues ever since changing form 32gb DDR5 (GSkill) to 96gb DDR5 (Corsair w/micron). When I change my monitor DP input to 1.4 (from 2.0), I get BIOS Everytime. If I go back to DP 2.0, it boots straight into Win11P.
So anytime I need BIOS, I just switch to DP 1.4. However, this can't be normal, and since it started with my new RAM, I'm left to assume it's doing something weird. Hope this helps others.
I came here looking for a solution as well.
I haven't read all the posts, but I just discovered the 'fix' for me. I just installed win11 on 'unsupported hardware' using Rufus, and lost the ability to access the BIOS so I thought it might be related to Rufus, but it's not. Here's what fixed it for me.
I disconnected the win11 SSD (clean install on new SSD) so I could see the BIOS. Poking around in the BIOS, under 'advanced' I found ACPI Configuration (which is apparently a way to set 'sleep' levels), and disabled it. Next boot, I could see/use the bios entry page, but the boot after that, I was getting 'waking from hibernation' and booting straight to win11 again, even though the bios ACPI remained set to 'disabled'. That bootup 'waking from hibernation' splash screen still showing up made me suspect that win11 was monkeying around with my bios settings, so....
I searched for how to disable hibernation and found this Microsoft troubleshooting page showing how to disable hibernation. Following the instructions (don't forget to 'run as administrator'; even the default admin account won't run as admin unless you force it) seems to have cured the problem for me. Hope this helps someone else.
To share my experience, same symptoms as everyone else. Could not access bios and advanced startup left me on a black screen. Originally, I had no problems but after a Windows 11 update started experiencing the issue.
I tried all the suggested items in this forum short of disconnecting my MB battery, flashing my BIOS, or disconnecting the boot drive. I tried different cables & monitors, disabled FastStart, etc. Nothing.
Finally I changed my refresh rate to 50Hz in the basic Windows Settings panel. I changed my refresh rate from 60Hz (old monitor) to 50Hz. Rebooted, saw the splash screen and was able to enter bios. Then it booted up in advanced startup mode too. I couldn't' find the post, but whoever talked about connecting to their TV making an effective switch to a lower refresh rate, your post was the one that did it for me.
Best of luck to us all!
