Error installing Exchange2016

Question

I was trying to install Exchange Server 2016 on Windows Server 2016, everything was going smoothly. But, unfortunately someone switched off my Machine where I have installed Virtual Box and running both AD and Exchange installation. It as in the process of installing Roles (5/14). When i started the setup again I am getting the below error.

Error:
The following error was generated when "$error.Clear(); 
$roleList = $RoleRoles.Replace('Role','').Split(',');
if($roleList -contains 'LanguagePacks')
{
& $RoleBinPath\ServiceControl.ps1 Save
& $RoleBinPath\ServiceControl.ps1 DisableServices $roleList;
& $RoleBinPath\ServiceControl.ps1 Stop $roleList;
};
" was run: "System.Management.Automation.MethodInvocationException: Exception calling "Reverse" with "1" argument(s): "Value cannot be null.

Could you please help.

As it seem a lab on virtualbox I would simply redo the VM from stracht, as it will be faster than trying to debug the issue.
