Unable to install Linux: Wrong Version of Linux Operating System

I am receiving this error upon starting the installation of Linux:
Checking installer requirements…
Checking operating system version: must be redhat-3, SuSE-9, redhat-4, UnitedLinux-1.0, asianux-1 or asianux-2
Failed
What option can I use in order to resolve this? What version of Linux is needed for this? And also, what are the complete system requirements on installing Linux?
