Built in device failure prevent windows 10 update to 20H2

I have a Dell Inspiron laptop with Windows 10 Pro. ver. 1909 (Build 18363.1198) with a dead AMD Radeon 7700M card.
To be able to use the machine I have uninstalled the driver for this card and disabled it in the device manager, this the laptop works fine.

Tried to update to Windows 20H2 through Windows 10 Update Assistant, got all green, but failed because the update program downloads, installs and enables the dead card and the result is a BSOD in the first restart, and when restarting after the BSOD the update program rolls back the changes and I'm back to Windows ver.1909.

Is there any work around? Can I stop the update program from enabling this card when restarting?

Thanks for any help.

See here: PowerShell disable and enable a driver - Stack Overflow

Instead of MCT, use and ISO then press Shift+F10 on the reboot where the problem occurs. That should get you to a Command prompt.
Then use Powershell followed by the necessary commands to disable the device. SOmething like this (from above link)

Powershell $d = Get-PnpDevice| where {$_.friendlyname -like "yourdevicename"} & $d | Disable-PnpDevice -Confirm:$false & $d | Enable-PnpDevice -Confirm:$false

Thanks Ztruker for your answer, but I wish I do not have to use an ISO as it will make the process much longer and will have to reinstall all software again, my time is really limited now

You will not need to "reinstall all software again".
- He is not suggesting booting from it.
- You will not have to reinstall anything afterwards.

Download the ISO then within Windows double-click on it to mount it then run its setup file. This is known as a Repair install or In-place upgrade.

The download might take time but you will probably not even notice any extra time that this method takes compared to the method you tried before.

I know nothing about the PS command he suggested.

If you post your Dell Inspiron model then somebody who knows it and has experience of updating it might be able to provide more specific guidance.

The important part here the ISO will not re-enable the card when restarting, correct?

I have no idea. I think that's what the link you were given [and the PS command taken from it] are intended to cope with.

And, since you'll be making a system image before you start, you can be confident of getting back to square one if it all goes wrong.

And most Dell Inspiron models have a Service manual that would guide you in removing the defective display card.
- It is up to you but if I was certain that an additional display card was defective, I'd remove it so I could be sure of avoiding any problems it might cause.
- Go to Dell Support then enter your Dell Service tag then go to Drivers & downloads where there should be a tab containing documentation downloads as well as the drivers you might normally go there for.

I like Denis's ( @Try3 ) idea of removing the defective video card if you can. That's an even better solution to your problem.

For the Powershell command, you need to read the article at the link I provided to understand how to find the name of the video device you want to disable then try running the Powershell commands using that name. I have no idea if it will work, just something I found that I thought might help.

Removing the card will definitely resolve the problem.

What is the full model number of your HP Envy Laptop?

Try3 and Ztruker thanks guys for your help.

This is a built in card is there any chance to remove it? The laptop is: Inspiron 15R SE 7520,

I can see that either way I'll have to backup everything before trying to fix this.
I'll go first to the removing option if I can, if not I'll go with the PowerShell option.

I'll do that and come back with the answer.
