errors on creating VHDX

[detox4you]

I keep getting fatal errors on the creating VHDX and I cannot pinpoint the cause of it. Hyper-V is installed, and I can create and run VMs with no problem.

My command line is:
.\BuildFFUVM.ps1 -make 'Dell' -model '3440' -WindowsSKU 'Pro' -FFUDevelopmentPath "C:\FFUDevelopment" -VMLocation "D:\HyperV\VMs" -Installapps $false -InstallOffice $false -InstallDrivers $true -VMSwitchName 'External' -VMHostIPAddress '192.168.0.76' -CreateDeploymentMedia $true -CreateCaptureMedia $true -BuildUSBDrive $true -UpdateLatestCU $true -UpdateLatestNet $true -UpdateLatestDefender $true -UpdateEdge $true -UpdateOneDrive $true -RemoveFFU $true -WindowsRelease 11 -WindowsLang 'nl-nl' -Verbose

This is the code you're failing on

    $newVHDX = New-VHD -Path $VhdxPath -SizeBytes $disksize -LogicalSectorSizeBytes $LogicalSectorSizeBytes -Dynamic:($Dynamic.IsPresent)
    $toReturn = $newVHDX | Mount-VHD -Passthru | Initialize-Disk -PassThru -PartitionStyle GPT

    #Remove auto-created partition so we can create the correct partition layout
    remove-partition $toreturn.DiskNumber -PartitionNumber 1 -Confirm:$False

Initialize-Disk is throwing an Access Denied.

Are you running as Administrator? The script requires this and will fail immediately if you're running as a standard user, but if you've modified the script and removed the check, then that check wouldn't happen.

Do you have any AV/EDR/XDR software that could be putting a lock on the VHDX? We create the VHDX and then immediately initialize it, so it's possible a file lock could be happening while we try to initialize.

I also notice that you have different paths for the FFUDevelopment folder and the VMLocation. You may want to just try having everything in the FFUDevelopment folder (no need to set the VMLocation parameter).

I have moved everything into one folder. Still got the same error. I've set a breakpoint in the BuildFFUVM.ps1 script at line 2624. I can observe that the new-vhd command works, the mount-vhd also works and I receive a disk number. It seems to fail on the Initialize-Disk command. If I execute this part manually it throws the same error, but I can see in disk manager that the disk has been initialized though no partition was created.
Everything is run elevated, I have tried VScode, PowerShell ISE and normal PowerShell. Same result. I am at a loss why this fails.

[rbalsleyMSFT]

That's odd. Did you also create a new VHD manually using powershell, or just debug the script and then execute the initialize disk step via the console? If not, I'd be curious if you could just create a new VHD manually as well and try to initialize it and see if that works or you see the same issue.

[detox4you]

Tried again including disabling real time AV scanning on drives. After some more testing it seems that the line:
Initialize-Disk $toReturn.DiskNumber -PartitionStyle GPT
will give an access denied error, but does execute the initialize disk part since it shows up in disk manager as initialized with GPT style after the error message is displayed and I set a break point there to stop execution.

So I changed the line to:
Initialize-Disk $toReturn.DiskNumber -PartitionStyle GPT -ErrorAction SilentlyContinue
and then the script continues.

Unfortunately it then fails on the line:
$systemPartitionDriveLetter = New-SystemPartition -VhdxDisk $vhdxDisk
on line number 4163 (in the #Create VHDX part). Error message:

$systemPartitionDriveLetter = New-SystemPartition -VhdxDisk $vhdxDisk
New-SystemPartition : Cannot process argument transformation on parameter 'VhdxDisk'. Cannot convert the "Microsoft.Vhd.PowerShell.VirtualHardDisk" value of type "Microsoft.Vhd

At line:1 char:61
+ $systemPartitionDriveLetter = New-SystemPartition -VhdxDisk $vhdxDisk
+                                                             ~~~~~~~~~
    + CategoryInfo          : InvalidData: (:) [New-SystemPartition], ParameterBindingArgumentTransformationException
    + FullyQualifiedErrorId : ParameterArgumentTransformationError,New-SystemPartition

The line just before it
$vhdxDisk = New-ScratchVhdx -VhdxPath $VHDXPath -SizeBytes $disksize -LogicalSectorSizeBytes $LogicalSectorSizeBytes
is exectuted with no error and does create a mounted disk visible in disk manager.

[rbalsleyMSFT]

Is it possible to try this on a different machine?

[detox4you]

I have tried on another machine with similar results. The step on line 2626
Initialize-Disk $toReturn.DiskNumber -PartitionStyle GPT
now works without error, but still the script stops at line 4160
$systemPartitionDriveLetter = New-SystemPartition -VhdxDisk $vhdxDisk

Included logfile:
FFUDevelopment.log

[rbalsleyMSFT]

Can you try again without running from PowerShell ISE? The log seems to indicate it's running from there. Send over the log from that run. Thanks, Richard

Same when running outside the ISE but I might be onto something: I downloaded the ZIP with the files again, deleted everything except my calling scripts and ISO files and ran it again. It does not give errors now. Nothing else changed except downloading from the source again. Running it now and it passed the point of error I had before. I think this was the 2409.1 version and now running the 2409.2 version.

[rbalsleyMSFT]

That's good news. When using VSCode with the PowerShell extension or ISE, things behave differently than directly from PowerShell. Hence the ask. But it's good that a redownload seems to have solved things. Let me know if it has any other issues. Thanks, Richard

First part now resolved it seems. It does get stuck on this error:

    + CategoryInfo          : NotSpecified: (:) [Mount-WindowsImage], COMException
    + FullyQualifiedErrorId : Microsoft.Dism.Commands.MountWindowsImageCommand

I resolved this by checking if the mount folder is created and if not create an empty one by inserting this before the command that failed (mount folder does not exist in the downloaded ZIP file of the code and it also gets deleted automatically):

        #Check if Folder exists
        If(!(Test-Path -Path "$FFUDevelopmentPath\Mount"))
        {
          #powershell create directory
          New-Item -ItemType Directory -Path "$FFUDevelopmentPath\Mount"
          Write-Host "New folder created successfully!" -f Green
        }
        Else
        {
          Write-Host "Folder already exists!" -f Yellow
        }

This now works. But I end up at an error I can't find the solution for. It now stops here:

Error 5 is typically access denied. Do you have the dism.log file?
