Salve kendrew!

"]I installed successfully Knoppix on harddisk with Lilo booting.

But then when I try to install Grub, there are problems:
Code:
knoppix:~$ grub-install /dev/hda
Could not find device for /boot: Not found or not a block device.
My idea is that grub-install will maybe write to /boot. Do you have
a writable /boot directory?
I haven't used knx-hdinstall or grub yet, so sorry to haven't more
ideas than this link http://www.gnu.org/software/grub/#documentation
wich I will use to learn grub.
Greetings,
