installation hardy error in grub-install

To install kubuntu hardy, I have an error when it is installed grub, the only way to make boot Hardy in the kernel is copied to / boot of other partition that already have installed grub (ubuntu gutsy installed on another partition)
Neither creates the file / boot / grub / menu.lst
Then I can not install grub to the shell.
grub> root (hd1,1)

grub> setup (hd1)

Error 11: Unrecognized device string
