Do you mean partition or slice?

The slice needs to be marked as bootable.  You can check this 
from the fixit boot using fdisk - 'fdisk ad0'  or  'fdisk da0'
presuming this is disk 0 and depending on IDE or SCSI.   
Then, if that looks OK, use bsdlabel on that slice (something 
like  'bsdlabel ad0s3' or 'bsdlabel da0s3' depending on IDE or SCSI and
presuming FreeBSD is on slice 3) from the fixit to see what you can 
learn from it.   Just doing bsdlabel with no other command flag will
print out information.
