Boot from a live CD, make a directory under /mnt which corresponds to
your partition layout, for example if you have / as sda2, make a
directory called /mnt/sda2. Mount your root filesystem under /mnt/sda2
and if you have any other partitions, mount them as /mnt/sda2/boot or
/mnt/sda2/usr and so on. Then chroot yourself into /mnt/sda2, which is

chroot /mnt/sda2

Now your inside your hard disk's filesystem. Without doing it right now,
I don't know if you need to mount the other partitions after you chroot
yourself in...

What you do next is something I don't know about under Mandriva. I did
under Ubuntu about 4 years ago:



Almost certainly things have changed slightly since then and I don't
know how Mandriva does things.

Hope that points you in the right direction, you just need to do the
Mandriva specific parts.
