cfdisk in DSl

ive been playing around in dsl (damn small linux) live for some time and i love the simplicity of it. but when i go into cfdisk to partition my hard drive, it says like
"Fatal Error:Does not have permission"

i am trying out Xandros desktop os 2.0 right now on my laptop. Can some one help me out with adding dsl to my computer with a dual boot.

Stupid question: you are doing this as root, yes?

technicly no
im using the dark root terminal when im entering commands for install but thats it

That would be a strong hint as to what you are doing wrong, then ....?

how do u get root access on a dsl live cd without using only a root terminal
