The basic steps are:

1. boot the livecd/usb
2. mount the drives you need (most people do i to /mnt) in the same structure as when you boot
   ie mount / at /mnt /boot at /mnt/boot and /home at /mnt/home (though /home is not normally needed)
3. mount the spical directory:
   

   sudo mount --bind /dev /mnt/dev
   sudo mount --bind /sys /mnt/sys
   sudo mount --bind /proc /mnt/proc
   sudo mount -t tmpfs tmpfs /mnt/tmp

4. if you need network access connect to the network and copy /etc/resolv.conf
   

   sudo cp /etc/resolv.conf /mnt/etc/

5. chroot into the target system
   

   sudo chroot /mnt

6. what ever you do now will affect the installed system not the livecd so install what you need, fix what you need then press ctrl+d to exit out the chroot
7. unmount what you mounted and reboot

Note that you should use the same architecture (32bit or 64bit) livecd as the installed system.
