Blank screen after enabling secure boot, any way to fix it?

[Aralon]

So i was trying to reinstall windows 10 in uefi mode(currently in legacy) so someone suggested to enable secure boot before putting the flash drive and i did so, to enabke secure boot i used the default gigabyte platform keys and then save and exit, as soon as i rebooted my screen was blank and the led codes on my mb were showing A9(bios setup is started),so i did a cmos reset using jumper and now it is stuck at code d6(no console output devices found) i have a z390 aorus ultra motherboard and i have no idea what to do now, no other forums have been helpful.I have high hopes that someone from here might just help me out.

Greetings,
So the community has a complete picture of your environment, please provide you full system specs, including BIOS rev.

Are you able to enter BIOS?  If so, please load Set Up Defaults and save. 

-Can't do that?  Please remove your MB Battery for 3-5 Min

What display device are you outputting to?  Are you using adapters of any kind?

Hey guys,

i got exact the same problem.

Here are my specs and explain what steps i already done.

Gigabyte Z390 Aourus Elite (bios ver. F10h from 2021.01.19)
Intel i7 9700k
2x 8GB HyperX 2133 Mhz
Samsung NVMe SSD 970 Evo 1TB at M2a port
Samsung SSD 850 Evo 250GB at SATA port

I tried to install Windows 10 Pro x64 from USB Stick (generated with the Windows Creation Tool & later with rufus in MBR Mode and NTFS Mode)..

I tried in various solutions and methods that ive been reed and learned in years of using PC's.. ->
cleared the NVMe
activated UEFI boot (with SATA Mode at AHCI and and in another installation on Intel RST..)
boot from stick
select the NVMe SSD, the first copy and extracting from installation progress.. we all now it ->
reboot
dont work... (pushed me into the Bios)
in bios activate the secure boot option
dont work...
installed the factory keys before the Installation
dont work...
installed the factory keys after the installation
dont work...
tryed without activating secure boot in another installation
dont work...
tryed with the option on "other OS" and the "Linux OS" in Bios/Boot options, and after the first restart pull that back to "Windows 8/10" option..
with clearing of Keys and hold Keys and pulled back to Factory Keys.......
I tried the second NVMe slot M2b
nada...

I got every time when i press f12 an empty boot option, that option push me into the bios ?!

(i cleaned the NVMe complete with disk part -> clean..., i have done all various creations from windows usb stick installation, i tried all various settings in Bios, i tried many solutions ive been read in the www... so)

Btw the installation on my 250GB SSD at SATA Port work without any problems :S

Greetings,
All of the Z390 based boards share similar characteristics.

There is no need to use anything but the windows media creation tool to make your W10 install media.  Forget Rufus or any 3rd party apps, they aren't needed. 

The install media can be used to install windows on a MBR or GPT partition.  I recommend GPT, but MBR works too.

F12 during post allows you to select a one time boot menu

Incorrect BIOS setting can get you into trouble, but should not be significant enough to keep you from installing your OS.

Start by resetting the BIOS to defaults.  Then start over.

Do not enable Fast Boot, its not needed.

Set CSM Support [Disabled]

Secure Boot [Enabled]

SATA Mode Selection [Intel RST Premium With Intel Optane System Acceleration] 

Note: Boot Option Priorities
Specifies the overall boot order from the available devices. Removable storage devices that support GPT format will be prefixed with "UEFI:" string on the boot device list. To boot from an operating system that supports GPT partitioning, select the device prefixed with "UEFI:" string.  Or if you want to install an operating system that supports GPT partitioning such as Windows 10 64-bit, select the optical drive that contains the Windows 10 64-bit installation disk and is prefixed with "UEFI:" string. In your case, this will be a USB Stick

Those are the key items you need for UEFI install

Insert your W10 boot media to a USB slot.

Save BIOS settings and restart

Tap F12, select your USB stick as the boot device

Begin windows install

When you get to the select target disk

Shift+F10 for a command prompt

Type diskpart, then press enter

Type list disk, then press enter

Identify your target...

Type select disk [?] ? will be either 0 or 1, then press enter

Now it will tell you that disk is selected

Type clean, then press enter

Type convert GPT, then press enter

Type exit, then press enter or just close the window

Back at the windows install GUI, now select the disk you just cleaned and partitioned GPT as your install target

Windows install resumes from there.

6-7 minutes later you'll have W10.  Thats it.

Hey i hope that youve write down this Instructions into another Topic and you copy pasteded me this ^^

In first, thanks 4 that.

I tryed to explain my 50 times various installations without much text above -

My installation progress is exact your explaining. 2 little things, i disconnectet all other devices before i booted and my NVMe cleaned in advance.

As I said before after windows is done with its first progress, the PC reboots and then I am in the bios, none of the boot devices that can be selected work :S

Hi,
I typed the steps from memory.  I've done it many times.  Its second nature.

Have you reset the BIOS to defaults before starting the install?

If you are ending up in BIOS, there is a hardware issue, incorrect BIOS setting or problem with the BIOS.  I noted you updated to a beta BIOS.  You may want to consider F8 or F9 if you continue to experience issues.

Chris step and take a breath. Start from Sq 1 by pulling the battery and clearing the cmos. Then going back in set your bios to default settings save and reboot. Then go back in set the time and date. Then go to the boot area to see if the NVMe SSD does shows up.

If doesn't then check to see if it is enable. Some boards do have a area where sometimes you have enable the NVMe drive. If you are using a USB drive to load windows. You have to plug that in 1st. Then go in the Bios and again to the boot area. Click boot option 1 and boot to the UEFI USB Drive 1st boot.

I have install windows 10 on well over 200 computers and almost every brand motherboard out there. On any motherboard don't start changing things in the bios before you install windows. On every board it is already setup to boot AHCI & UEFI.

You just can't stick in the USB drive and think the motherboard will boot to it. Plus people stay out of the bios unless you really know what the changes you making and why you made them. I learn years ago not to make any changes other things that you really need to changes.

On secure boot and CSM I don't ever change them unless I really have to.

Now if does boot to install windows once you get to the screen where ask you to do upgrade or custom. Click custom and on the next screen if you have only the 1 partition on the drive. Or if you have other partition you will have to delete them to get back to 1 partition.

Once that is done then click on that drive and then click new. It will ask if you want to do this just click OK till the drive is setup. You should have 3 partition. Then just make sure the large partition is highlighted and click next. You are on your way.

Now once windows is installed. It will start asking question. If you want off line account disconnect from the internet. Windows doesn't give you a option to make a online or offline account. If you are doing the offline account once you have enter a name plug the internet back in.

I try it today,

after Bios reset, I have to start up and press F12 and select my stick UEFI: Lexar USB Flash drive 1100

Then I cleaned the drive with disk part.

Created the Partition in the Windows installation. (screenshot)

After reboot, the computer boot up into bios. (screenshots)

Did you install windows? If you did there will be a windows boot manager you boot from in the bios. If you just made the partition in the windows installation and reboot you don't have windows installed.

[shadowsports]

If the system is restarting and booting into BIOS, you have one of the following:

Bad BIOS flash
Incorrect BIOS setting(s)
or
A faulty piece of hardware

Is windows installed or not - (what dmdilks asked)?
