WIndows 10 can't see BIOS while using Dedicated GPU

Irish_PXzyan · Aug 7, 2015

Howdy lads.

I'm having an odd issue here with Win 10 which involves the pc booting without seeing anything prior to signing into an account!

So when I want to access the BIOS I can't see the boot image but I can press the DEL key to get into the BIOS but I can't see anything!

I can see it when I use the integrated Graphics instead which is a bit odd!

Why would this be happening lads?!?!

Sounds like a form of fastboots been enabled, does MSI have any "Reboot To UEFI" equivalent?

Irish_PXzyan · Aug 7, 2015

I have disabled Fast boot and MSI fast boot from the BIOS and it still happens!
MSI has a Fast Boot app which always me to turn on or off the fast boot option and also has an option to enter BIOS but it just ends up showing a blank screen again

Am I the only one who is having this issue?! :L

plug the hdmi or vga to motherboard or use dgpu without motherboard connection.

The BIOS/UEFI has no relation to what OS you're using. You should be able to access BIOS/UEFI even if there is no HDD/SSD attached (menaing you also have no OS).

Either the board is dud or you have some option set that doesn't display anything on boot. Press F1, Esc or Del during powerup of the system, you should get the BIOS/UEFI menu that way...

If your using a TV make sure things are not going out of range when trying to enter bios.

Had a simler issue with my TV where it would basically go out of range when trying to get into bios because TV was set to auto aspect ratio.

But fast boot will stop you getting in to the bios and leaves 2 ways to get in to it one being though the OS the other by a bios reset.

Fast boot can disable the keys that allow you to enter the bios, as i said above there is 2 ways, in fact it warns me of this when selecting it.

If i removed the boot drive to this system i am on now i would not be able to get in to the bios unless i reset the bios.

I can press the DEL key to get into the BIOS but I can't see anything!

That sounds really odd.

Nothing I try does anything sadly :/ I can get into BIOS easily by pressing the DEL key but like I said, I actually can't see anything while the dedicated graphics is the source :L But once I connect the HDMI cable to the onboard graphics I can see the BIOS no problem!

Like what on earth is going on!!! I have never heard or faced this issue ever so I just don't know what to do at all now :L

Onboard GPU sees the entire boot phrase and the dedicated GPU only sees the windows login section?!?! Oh dear ^^

It is becuase of the onboard GPU is first boot device and has not been disabled. Totally normal. Most boards will turn off integrated video when a discrete card is installed, but if you can swap and see, then obviously it is not disabled.

This issue is common in Hackintoshes with a dGPU.

There should be a setting for integrated graphics with options PEG and IGD. I think PEG enables the dGPU and supposedly disables iGPU, but I'm not sure. All I know is that I needed to set to IGD, which is supposedly for iGPUs, when I installed Yosemite without my R7 265 in the system, but I can still see the BIOS screen just fine, and if I swap the display output from the card to HD 4600, it recognizes instantly even on PEG.

Thanks lads I will have to give this a go when I get back onto to the pc and hopefully this will clear things up ^^

I did have it disabled but perhaps it was enabled once Windows 10 was installed?????

Did you ever fix this issue? I am having the same issue right now

Go to your BIOS and disable the integrated GPU (or set it to show picture on dGPU first)

KvngSteven · Dec 22, 2022

It doesn't work, also I can't see the BIOS when the gpu is plugged in even while connected to the onboard graphics, I litteraly have to disconnect the GPU to even be able to see the bios on the integrated gpu

My Graphics Card has Dual BIOS, One for Gaming and another for Mining. The mining one shows me the BIOS but it's all pink

Does this BIOS look legit and normal?

Can you install the drivers? I think your GPU might be broken.

Sometimes this problem can be sorted by using a different HDMI port on the back of the card.

On a few of my cards I cant see the BIOS screen unless I have the HDMI cable connected to the bottom most port on the back of the card.

So make sure to try all the ports on the back of the GPU.

I believe this is what fixed this issue for me years ago... Certainly give this a try as weird as it sounds!

Yes, I can still drivers and play games on it, I know it's not broken because device manager and MSI Afterburner and GPU-Z detecs it

I already tried HDMI and DVA they both give the same exact problem

Sorry missed the part where you said there was a mining BIOS and gaming BIOS.

Have you tried both CSM and UEFI options in the BIOS when using the on board graphics to enter the BIOS?

GPU and RAM Clocks are showing 0 because windows will not load the AMD drivers with mining or modded BIOS has it will fail the windows driver signature detection.

You can try patching the drivers or if you not mining flash a proper / original BIOS with UEFI support. I can't help with that but others on here may be able to.

I never mined, I bought this card from a miner though. Do you think he modded the Gaming BIOS? Because that screenshot is from me using the Gaming BIOS.

It seems that the picture you posted is from a mining BIOS.
This is the one you know it was used for mining purposes ?

It is the Gaming BIOS, I switched the switch to Gaming BIOS on my GPU

Indeed, that bottom port is the master port where the card doesn't activate all of them without the driver loaded. I therefore have my primary monitor connected to it.

I think the guy I bought it from definitely did something to the Gaming BIOS and modified it

Can you help me flash the original Gaming BIOS?

OK, from the picture you posted earlier i can confirm that something is not right at that BIOS
