The boot manager has nothing to do with /etc/fstab,
which "happens much later". If you encounter a problem
at an early booting stage, the reason is to be searched
Maybe... is the boot manager damaged or absent? Check
the partition properties with gpart. In worst case,
re-install the boot manager (with gpart or bsdlabel,
depending on how you have partitioned your drives).
Are you sure the system is trying to boot from the
correct drive? Can you interrupt at the boot prompt
or the loader prompt, or don't you even reach those?
