3. Hello there.

   Is there a way of making MDT ask the user which hard disk to install windows on?

   To explain, im in the middle of upgrading my gaming rig in my lab to an m.2 SSD from a SATA one. I would like to avoid windows being intalled onto the SSD if i can.

   Thanks

   1. Microsoft Deployment Toolkit (MDT) does not have an out-of-the-box option to prompt you to choose the hard disk during deployment. However, you can achieve this by creating a custom script that prompts you to select the target disk and then modifies the task sequence variables accordingly.

      Here’s a step-by-step guide on how to create and integrate the custom script into your MDT task sequence:

      1. Create a PowerShell script (e.g., SelectDisk.ps1) with the following content:
      


      1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

      $disks = Get-Disk | Sort-Object -Property Number $diskMenu = @() foreach ($disk in $disks) { $diskMenu += New-Object PSObject -Property @{ DiskNumber = $disk.Number Size = "{0:N2} GB" -f ($disk.Size / 1GB) MediaType = $disk.MediaType } } if ($diskMenu.Count -gt 1) { $selectedDisk = $diskMenu | Out-GridView -Title "Select the target disk for Windows installation" -OutputMode Single if ($selectedDisk -ne $null) { $TSEnv = New-Object -COMObject Microsoft.SMS.TSEnvironment $TSEnv.Value("OSDisk") = $selectedDisk.DiskNumber } } elseif ($diskMenu.Count -eq 1) { $TSEnv = New-Object -COMObject Microsoft.SMS.TSEnvironment $TSEnv.Value("OSDisk") = $diskMenu[0].DiskNumber } else { Write-Host "No disk found" exit 1 }

      This script retrieves all HDDs on the system, presents them in a grid view for selection, and then sets the “OSDisk” task sequence variable to the selected disk number.

      2. Save the SelectDisk.ps1 script in your MDT deployment share, for example, in the “Scripts” folder.

      3. Open the MDT Deployment Workbench, and navigate to your deployment share.

      4. In your task sequence, create a new “Run PowerShell Script” step:

      a. Right-click the “Preinstall” group in the task sequence.
      b. Choose “New” > “Run PowerShell Script”.
      c. Name the step, for example, “Select Target Disk”.
      d. Set the “PowerShell script” field to “.\Scripts\SelectDisk.ps1”.

      5. Modify the “Format and Partition Disk” step:

      a. Click on the “Format and Partition Disk” step in the task sequence.
      b. Change the “Disk number” field to “%OSDisk%” to use the selected disk number.

      6. Save the task sequence and update your deployment share.

      Now, during the deployment, you will be prompted to select the hard disk for Windows installation. Note that this script assumes that the target disks are of type ‘HDD’.
