How to trigger Stand Alone TS media in bootable USB using a commandline

Hi All

I have special requirement where the offline task sequence media needs to be used to image the laptops, but in following manner:

- TS media with autorun is burnt to a USB as bootable

- User being logged in to the machine, if he wants to reimage the machine, he just plugin the USB and run launchmedia.bat or any other custom script.

Is there any possibility to achieve the above requirement.

Thank you

Regards

Ramesh
