problem with mounting the /dev

hi everyone,
I recently did a reinstall of windows vista and my grub is gone.
So I would like to reinstall it with grub-install command using a fedora live cd
I did the following steps :-
booted up on the live cd
created a temporary mountpoint
mounted my linux partition
changed dir to the mounted linux partition
then executed following commands
chroot .
mount /proc
mount /dev
But then I got the error :-
mount: unknown filesystem type 'devtmpfs'
The next step would be to do
grub-install /dev/sda

But the mount /dev command failed and I am stuck.
What should be done ? plz help me out
thanks in advance

The correct steps for a chroot are
mkdir /mnt/fedora
mount /dev/sda? /mnt/fedora
mount -t proc none /mnt/fedora/proc
mount -o bind /dev /mnt/fedora/dev
chroot /mnt/fedora /bin/bash
