4.9, 5.1 boot failure after install

I've tried both methods. Letting the install program WRITE to FDISK 
upon completion and writing directly after making the partitions and 
setting the labels. Writing during the install gives the prompt that on 
new installs the routine will write later, do I really want to do it now. 
When I click yes I get the prompt that it is successfully written.

I assume that when I return to fdisk it will show a current setting (ie. 
active or not). Is the install operating on a ramdisk doing a final write 
on completion? I read one place that a person had the same problem 
and installed redhat successfully then reinstalled FreeBSD and the 
geometry was changed in fdisk. Is there a geometry issue?
