 ### Prepare a VM
 
-If you're creating a new VM for the image, use a first party Azure Marketplace image supported by Batch as the base image for your managed image. Only first party images can be used as a base image. To get a full list of Azure Marketplace image references supported by Azure Batch, see the [List node agent SKUs](/java/api/com.microsoft.azure.batch.protocol.accounts.listnodeagentskus) operation.

 - Ensure the VM is created with a managed disk. This is the default storage setting when you create a VM.
 - Don't install Azure extensions, such as the Custom Script extension, on the VM. If the image contains a preinstalled extension, Azure may encounter problems when deploying the Batch pool.
