Käännös - Englanti-Venäjä - Hi. I am helping to develop a Linux distribution...

Hi. I am helping to develop a Linux distribution that is going to be Delivered in over fifty languages. I am creating a start button (like Windows) in the native languages. Because it is context dependent, a direct translation does not work most of the times. Can you please tell me what is the best translation for "Start" in this context?
Thanks

As it transtated in Russian version of Windows =)
