help

[Luis Enrique Bonilla B.]

hi, I'm really new at this, i'm trying to install gentoo on my pc, but while 
i was doing it the docs said i should type # grub-install 
--root-directory=/boot /dev/hda, after i did this it shows:
More than one install_devices?
usage: grub-install [option] install_device
install grub on your drive

i really don't know if it's you i need to ask help to, but i don't know whom 
else to ask.

hope you can help me because it's the first time i'm in touch with linux and 
i need some (a lot ) help
thnx
