Reinstall os x from snow leopard with no start up or recovery disks.

What is the process for reinstalling lion from snow leopard when there is no start up disk, no recovery disk and the 'set up and install a new copy of lion' from utilities isn't available via internet recovery with apple id log in? One disk separate from the main disk called 'mac os x install dvd' has been erased and on a normal restart allows a flashing folder with a question mark.
