Joomla Auto-installer won't work with sample_data

Hi I have been trying to get the Joomla script to install under Virtualmin with my sample_data.sql. If you install Joomla manually you get a prompt to use this file. But with the auto script installer it’s not working. I even tried placing the files in the installation/sql/mysql folder, but I just cannot get it to work.

The reason I want the Virtualmin installer to control Joomla is because the interface works the same and when installed manually, things start acting funny.

Any help is appreciated.

Thank you,

after installation, rename the configuration.php and browse to the website. you’ll see the installer again and then follow the steps.
I haven’t tried this, but seems a logic step to me
