We are using Physical server and are in process of Automated “ubuntu-12.04.1-server-amd64” OS installation on it.

There are two HDD for OS installation purpose and there are RAID1 relation between them. This setup has been done through BIOS.

The kickstart configuration file looks like this:

#Generated by Kickstart Configurator

But I am getting the below error : No root file system is defined

Please suggest on this. Do we need to do any modification in kickstart configuration file. Any help in this regard will be very helpful for us.

The automated Ubuntu OS installation is successful in Virtual Machine(VM) with the above ks.cfg (kickstart configuration file ) but failing in case of physical machine. Please suggest on this and if possible provide the new ks.cfg file to resolve above problem.
