type ls /boot
(i think it's valid command)
you need to check if there is any kernel at all, perhaps you can use it (there was some command to load kernel, but i don't remember exactly)
in case you ain't got kernel (for got to install one??? is it possible, maybe, idk)
put CD and do post install configuration
go to distributions and select kernel
install it and reboot, with luck everything will be fine.
