# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that

o que esta errado? e como eu do permisao?

a pardisao nao grava

se for o /dev/sda2 então faça o seguinte

Citando:

Usei o super grub e nada.
Vou dentar o seu comando.

consequi montar o sda2 em /mnt/disc/hd
com este comando # mount /dev/sda2 /mnt/disc/hd
porem nao estou consequindo usar grub-install

usei asim # grub-install -- root-directory=/mnt/disc/hd

usei tbm

[root@localhost disc]# grub-install /dev/sda2

Could not find device for /dev/mapper/livecd-rw
