   * **Option 2: Azure CLI Guide**

     1. From a different machine (any other machine you can access your Azure account from), log in to your account with Azure CLI (`# az login`).

     2. Execute in the Azure CLI:

        1. Show the disks you have available and make sure your new disk exist:

           `# az disk list --output table`

        2. Stop the VM you are restoring the snapshot in:

           `# az vm stop -n <vm_name> -g <resource_group>`
        3. Swap the new disk into the applicable VM:

           `# az vm update -n <vm_name> -g <resource_group> --os-disk <resource_id>`

           Note: You can find the Resource ID in the disk properties in Azure Portal.
        4. Start the VM:

           `# az vm start -n <vm_name> -g <resource_group>`
