PC NOT BOOTING TO BIOS AFTER ENABLING SECURE BOOT. HELP PLS!

[Razero]

To reinstall windows I disabled csm support and restarted back to bios no problem, but some forumer suggested i switch on secure boot which i did with the default gigabyte platform keys enabled and at first it was not opening bios but was stuck on code 78(acpi initialization) and on powering off and on it is on and vigorously pressing F2 and F12 and Del now it is showing code A9(Bios setup is started) on every startup regardless of me pressing any buttons on restarting but screen is blank and i cant open bios.. why is this happening, can anyone help me?

Clear the CMOS first. Follow the instructions in your motherboard manual on how to do that.

cMOS reset, also can try taking out the motherboard battery. should work.

Reset CMOS (if you struggle to find the pin location in your manual you can pull the coin cell battery for a couple minutes).

 

Depending on how sketchy the websites are you visit and how up to date your anti-virus applications are Secure Boot isn't a totally necessary BIOS feature. For some bootable software it can be necessary to disable it (as I learned installing Ubuntu Server in a HyperV VM).

 

If the system works with it enabled then enable it.

If the system doesn't then leave it disabled.

 

Basically it prevents people from hijacking your boot drive during the boot process but this method of hacking isn't a every day concern for consumers. There's much more common viruses, malware, & worms to worry about at the OS level and these are handled by your anti-virus.

The guy i was talking to here suggested it, if i m unable to boot windows, that i can understand, but even bios not appearing? Can you explain why is this happening? Also i  might sound noob but my cmos battery is covered by the graphic card which i m too much of a chicken to take out, the clr_cmos 2-pin is there, the manual says i can use a screwdriver or paperclip to short it since they havent packed up that plastic connector thing but after the last fuck up i m too afraid to try that, Is there no other way? If not(which i kind of think yes) then i ll have to wait a day or two before i cld gather up courage to do it or bring a technician,In which case i am just supposed to unplug my pc and put a paperclip connecting those 2 pins for 5 minutes right?

Usually when Secure Boot is enabled and it sees something it doesn't like a page will pop-up telling you about it. For your whole computer to basically fail to properly POST makes me wonder if something else is also wrong.

 

Did you ever try disconnecting your drives and seeing if that lets you back into the BIOS?

I thought bios never depended on the drives? Also I can't access the hdd currently because it is on the separate part with the psu... the motherboard led codes suggests that bios setup is started but the monitor doesnt show it?

For BIOS to boot no it doesn't but since Secure Boot is our suspect it's going to check the drives. If there's no drives to check it might let you back into the BIOS to disable it again (at least temporarily).

Well i dont think thats the problem because my windows was legacy and i have csm support disabled and what was uefi was the bootable usb drive so the boot loader should completely ignore the ssd/hdd and check the usb only, but i have already checked by removing it too 

 

I did some googling and i think i might have found the culprit.. most of the people having problems like me have used custom platform keys in the secure boot key management settings, i selected the gigabyte default PK so i didnt think it could ve been the culprit but now i do.. Can i ask if reseting cmos will disable secure boot or atleast reset the platform key settings? 

 

Edit:Oh my god! i just made a discovery! it didnt solve the problem but i think this information might be able to tell you what is the exact problem, i just plugged the usb back in,no boot as usual but the the led codes changed from before, without the usb it was stuck A9(Bios setup is started)but was showing no bios, but with usb plugged in the led code was stuck at 78,which meant acpi initialization, so i assume that hat the secure boot issomehow involved in this, what are your thoughts?

Resetting CMOS will reset your BIOS settings to Factory Default. If secure boot is disabled by default then yes it will disable it again.

[Razero]

Disabled or not i m sure it was in such a state that allowed bios to boot without problem

I reset the cmos using jumper, it did reset because my rgb fan colour changed and my xmp profile disabled but now i m having d6(No console output devices are found) what happened to it now?

What model is this motherboard? It appears D6 may have something to do with the GPU.

Motherboard is gigabyte z390 aorus ultra and i tried using hdmi on the motherboard's hdmi slot and still getting d6 error, and my gpu rgb lights are still working along with the gpu fans. Also my problem seems to be similar to this:https://forum.giga-byte.co.uk/index.php?topic=13373.0 

But i cant find a way to force backup bios (manual says its supposed to be auto)

Unless your CPU has an iGPU the onboard video ports won't do anything.

 

Did you try putting the GPU in another slot?

i thought i7-9700k had IGPU?

I don't recall you informing us of what CPU you have. It does have an iGPU. Did you try unplugging the dGPU before plugging into the iGPU?

Well, i might have forgotten to mention... I take it you mean the gpu which is plugged into my pci slot? i had unplugged the dp cable from that gpu and then plugged in the igpu, could it be that i have to disconnect that gpu from the pci slot to make this work?

It's not necessarily that you HAVE to. It's just that depending on the hardware sometimes due to default settings in the BIOS the iGPU won't do anything when a dGPU is connected (still in its PCI_e slot).

 

Not to mention if this has become a GPU issue it's best to fully remove it. If the issue persists the GPU is fine. Based on what brought us here (Secure Boot) I have to assume it's fine but your error code suggests it's something to do with GPU right now so we're investigating it.

Anyway i could force the backup bios? The default method of keeping the power button pressed till it powers on and then off is not working and i m sure it didn't activate the backup bios yet because last time i did a cmos reset the fans had to adjust their direction and the rgb lights took a while to work and for some reason i think there is a good chance that i may have this problem:

 https://forum.giga-byte.co.uk/index.php?topic=13373.0

which were confirmed fixed by more than 2 people using backup bios

 

I even posted a thread in both uk and us forums and no one has replied for 2 days

Praise be to Allah, I was very confused and did not find useful solutions, so I was facing this problem, I also cleared CMOS and it didn't work, and after I despaired,

I took the device to the vendor, and it worked for him and it was due to changing the vga card, but not because my card was disabled, but because I had disabled the csm support option to be able to activate the safe boot.

after I reset these two options (disabled secure booting and enabled csm support) the card returned compatible praise be to Allah.
