# MDT: Use OSDCloud DriverPacks in a Task Sequence ## Preinstall Phase ### Modify Inject Drivers step Modify your Task Sequence to include drivers from the **OSDCloud WinPE x64** selection profile that was created in the [**WinPE Drivers**](/osdcloud-v1/integration/mdt-add-osdcloud-winpe-drivers.md) configuration. This will ensure that you have the minimal Network and Disk Controller drivers needed to startup the Operating System to first boot

## Install Phase ### Add Run Command Line step Add a **Run Command Line** step to your Task Sequence prior to **Install Operating System** to load the [**OSDCloud Sandbox**](/osdcloud-v1/osdcloud-sandbox/sandbox.md). This will ensure that you have the latest OSDCloud dependencies in your WinPE Session. Use the following for the Command line ``` PowerShell -ExecutionPolicy Bypass -Command "Invoke-Expression (Invoke-RestMethod 'sandbox.osdcloud.com')" ``` Make sure you do not 'Continue on error' because if this fails to load, then you will probably not be able to download DriverPacks

## Postinstall Phase ### Add Run Command Line step After Configure, add a Run Command Line step called **OSDCloud DriverPackMDT**. Use the following for the Command line ``` cmd.exe /c start /wait PowerShell -ExecutionPolicy Bypass -Command Invoke-OSDCloudDriverPackMDT ``` Start in should contain the following path ``` %OSDisk%\Windows\System32 ``` Options should include **Continue on error**

### OSDCloud DriverPackMDT Step for VM Testing If you want to test downloading and applying a DriverPack in a Virtual Machine, modify the above step to specify a Manufacturer and Product. I select a Lenovo as the DriverPack as HP and Dell do not show progress in the Specialize phase during the DriverPack expansion ``` cmd.exe /c start /wait PowerShell -ExecutionPolicy Bypass -Command Invoke-OSDCloudDriverPackMDT -Manufacturer Lenovo -Product 21DC ``` ## Test a Deployment The following screenshots are from a Virtual Machine emulating a Lenovo P1 Gen 5 device

This part may take 5-10 minutes. Most DriverPacks will not show any progress

Lenovo is the exception where you will see the expand of the DriverPack

PPKG DriverPack expand and apply in Specialize will be saved in C:\Windows\debug
