OK. So it looks like you have succeeded with stage 1 and 2.
At this point the boot slice is known - the boot process knows where to find
defaults. 
After that stage 3 should be auto-executed, but it does not.

At this point check if you have /boot.config by chance. This file, if exists,
may contain options modifying stages of the boot process, in this case
the transition from stage 2 to 3 is of interest.
Check it out and, if applies, read BOOT.CONFIG(5) and its examples.
