Copy this into settings.xml

<?xml version="1.0" encoding="utf-8"?>
<Settings>
<BootEntry Drive="C" Path="VHD\Private.VHD" Description="Second Partition" />
</Settings>

Copy this into disk

select vdisk file=c:\VHD\Private.vhd
attach vdisk
assign letter=E
exit

Execute the following command in a cmd.exe with admin rights:

Powershell Get-ExecutionPolicy

Powershell C:\Install\Private\Setup.ps1
