Hi,

I wanted to try to update my computer to Windows 10 20H2, but no matter what I try, I just get a Black screen.
I have been trying, on and off, for the last 4 months to install it. And no matter what I do, I just cannot update my computer. I have even tried, as offered in my other post, about disconnecting all the ancillaries. And I have even disconnected all of the extra drives, leaving only the C: and F: Drives as the only operational partitions on the same SSD drive.

And nothing I seem to try, helps to sort out how I always get a failure when installing the 20H2 update.

I have just spent 7 hours, trying again to install the update, via an ISO I downloaded from Microsoft (which includes the 20H2 update). I used a program called Rufas to make a bootable USB drive from the ISO file. I then used a program called MobaLiveCD, to test the USB drive as a virtual drive on my computer. With everything connected as I usually have it.

The result is that the USB drive is bootable, and I can see the Windows Logo on the small test screen as I was hoping. But, I then get almost instantly a black screen, with just the letters QEMU at the top of the small screen surround.

My computer specs are:

Tech Support Guy System Info Utility version 1.0.0.9

Does anyone have an idea about what is going on, or that I am doing wrong?

Many thanks in advance.

Gary

I suggest using an alternative route, gazza. Go here and click on the Download tool now button under the sub-heading for Create Windows 10 installation media, and then download the file in a location of your choosing.

Run the file and then follow the instructions under the sub-heading Using the tool to upgrade this PC to Windows 10. I've used this method successfully on a lot of PCs, including version 1909 which you have installed.

Hi,

Thank you for the reply, I have tried the Creation tool before. But I have not seen the installation page from your link. And, I am afraid to say that I have the same result as before, the Blue "Installing Windows" got to 100%.

But when my computer rebooted, to the "Working on updates" screen, it got to 48%. And again it crashed to a Black screen. So I had to hold in the power button, so that I could restart the computer, and then undo the previous changes.

Sorry to see you're still having issues, gazza. Here's what I recommend next...

Hold down the Windows and X keys together to bring up the menu and left-click on Command Prompt (Admin). Once the Command prompt window opens, type (or copy & paste) the following into it and then hit the Enter key:

rundll32.exe pnpclean.dll,RunDLL_PnpClean /DRIVERS /MAXCLEAN

Once that has completed, reboot the PC and then try re-running the Media Creation Tool to initiate the update process again.

Why don't you install version 21H1.
Have you tried making a fresh install. Try removing your c drive and if you have a spare SSD or HDD just try it out in there to see if it installs.

Hi,

lochlomonder - I followed your instructions, but I found that Windows + x keys, did not bring up the (Admin) Command Prompt. I had to use - Start, All Programs, Windows System, Command Prompt (Right click Admin) to clear the Drivers.

I rebooted, and ran the Creation tool again, this time it went through like last time. But on this occasion, the second installation screen, with the whirly wheel froze at 48%. And again I had to reboot the computer, back to how it was before.

texasbullet - I was led to believe, that 20H2 had to install before 21H1. I have tried I think 4 Clean Installs, with 2 of them with the basic parts of a computer connected. 1 x monitor, mouse, keyboard & speakers. And even the extra drives all disconnected on one occasion.

I was going to delete all of the partitions on Drive 0, if the USB bootable drive worked. Just to see if it was that could be causing the problems. Before I do another Clean Install.

You should get rid of Bullguard Antivirus BEFORE you update Windows 10 from Version 1909 Build 18363 to Version 21H1 Build 19043.
Using a third-party antivirus app in Windows 10 can cause various issues with it.
Windows updates failing to install is one of the primary issues.

I agree with texasbullet.
Doing a clean install of Version 21H1 Build 19043 will give your computer a fresh start and get rid of the clutter and issues that are in it.

When making a fresh install you need to go to the custom menu and delete all partitions from the SSD or HDD and follow in screen instructions. When prompted to enter activation key select "I don't have an activation key" and also when prompted to connect the internet just skip it.

Thank you for the replies, and based on them, I have downloaded an official Windows 21H1 ISO file, and tried again to make a bootable USB drive with it. (I have disabled the Bullguard antivirus, while I was making these drives.)

The first run I did making the drive with Rufus, was with the settings for Partition Scheme - GPT, and the Target System - UEFI. The drive seemed to be ok, but when I tested it with MobaLiveCD. I got this screen about I need to change the settings to BIOS.

So I ran the Rufas program again, with the settings for Partition Scheme - MBR, and the Target System - BIOS (or UEFI - CSM). I rebooted the computer, and put the USB drive in, and it is now not showing on File Explorer. But it is showing in Disk Management, as Windows 10 21H1 ISO (as I named it). I changed the Drive Letter and Path and it was assigned K:. And it now shows in my File Manager.

When I tested it with MobaLiveCD, the program ran as I expected, and just like the 20H2 update, I got a flash of the Windows logo page. And then I just got the black screen again.

Thank you for all of the help, but it seems that there is something seriously wrong with either my computer or the Windows updates. At least by using the virtual drive MobaLiveCD, virtual drive checking program. I have not had to dismantle my computer each time to see if the USB drive works or not.

Why are you going through the complicated process of using Rufus to create a bootable install USB flash drive with Windows 10 21H1?
Using the Media Creation Tool that Microsoft provides is a much easier and quicker way to do it.

Thank you for the reply.
I have tried the Media Creation Tool before, but I have always run into the same problem with the Black screen at the end. As I am not sure if I am creating the USB drive wrong or not. So I wanted to see if it would work, before I use it to try another clean install.

Here is the users manual for your motherboard. See page 2-1 for bios setup.
If you have more problems with errors on your HDD and if you have a spare computer I would just remove the HDD from your Asus computer and connect it to your other computer and reformat it in there. Make sure you format it either in NTFS or MBR and replace it back to your Asus computer.

Hi,
Thank you for the replies.

I used the 21H1 updated ISO file, and I got the computer to boot up and run the updated Windows 10.
So that problem has been solved.

But, I have had to go back to my system restore version of Windows 10, as some of the software I use daily, would not see the backups, on my other drives. So I could not re-install the programs, as well as see the diary that I use.

So, seeing as Windows Update will not install the 20H2 update, without causing problems and black screens. As well as block all other updates to my computer. I am now wondering if the 21H1 update is available separately, so that I can bypass Windows Update?

When making a fresh install of W10 you can leave the internet disconnected until done. After that you can connect the internet and download updates. You may also want to check on the optional updates for driver updates for your computer.
