I want to change the bios setting to boot from hd1 but hd1 is not currently 'bootable' . How do I make hd1 'bootable' from a bios standpoint without running grub-install .

We do not know exactly what partition holds your /boot filesystem, but 
what you need o write an mbr on hdb is probably a slight variation on 
this, wherein /boot is in hdb1:

grub> device (hd0) /dev/hdb
                                                                                
grub> root (hd0,0)
 Filesystem type is ext2fs, partition type 0xfd
                                                                                
grub> setup (hd0)
 Checking if "/boot/grub/stage1" exists... no
 Checking if "/grub/stage1" exists... yes
 Checking if "/grub/stage2" exists... yes
 Checking if "/grub/e2fs_stage1_5" exists... yes
 Running "embed /grub/e2fs_stage1_5 (hd0)"...  16 sectors are embedded.
succeeded
 Running "install /grub/stage1 (hd0) (hd0)1+16 p (hd0,0)/grub/stage2 /grub/grub
.conf"... succeeded
Done.
                                                                                
grub> quit
