I usually do something like this:

boot rescue CD

- Mount root partition from hard drive on /mnt/root0
-  cd /mnt/root
-  mount other partitions from hard drive on their appropriate 
locations in /mnt/root, so if you have a /boot, mount it to 
/mnt/root/boot, etc.
-  chroot /mnt/root
-  Now you should be able to run mkinitrd as normal, since you are 
effectively running off your install on the hard drive.
