reinstalling lilo

Hi, I need to reinstall lilo, browsing in the internet i found the next steps:
a) boot using knoppix (i´m using 5.0)
b) root@tty1[#] mount /mnt/hdxx (in my case hda5)
c) root@tty1[#] chroot /mnt/hda5
d) sh-2.05b# /sbin/lilo

AND HERE IS THE ERROR MESSAGE:
Fatal: open /dev/hda: Permission denied

Reading this, I undestand that I can´t enough right over hda (hda1: xp, hda5: mandriva) but I don´t know why because I´m logged as mandriva root (sh-2.05b) so... what am I doing bad?

Howdy htamayo!

Could you clarify your step (b) command, it should be:

Code:

---

mount /dev/hda5 /mnt/hda5

---

I am assuming that directory /mnt/hda5 exists and that the device you want mounted is hda5.
