/etc/fstab does not have a line for /bootRight, it doesn't matter where you mount it. It's just to verify the existence of the /boot directory and the kernel in it, which should be in that partition if it indeed was once bootable.
They don't exit because /mnt/boot does not exist. No file or directory exist.The bootloader does not mount the filesystem, it just pulls the kernel out of it. You're supposed to be using the installer USB drive to mount ada0 on /mnt and check if /mnt/boot/loader and /mnt/boot/kernel/kernel exists
Are you sure you’ve mounted the drive’s root file system correctly? Please share the output fromThey don't exit because /mnt/boot does not exist. No file or directory exist.

.I had two drives on this machine both with FreeBSD. I removed one of them to use on another machine.
No I can re-install it if need be. Let me know what to do once I place it back into the box.Well, now that I think of it, you probably removed the one with the bootloader on it, even if this one is the one with the system that was booting, even if the kernel mounted this disk as root. boot(8) got installed to the FreeBSD disklabel, but didn't get hooked up right and you never noticed because you used the loader on the other disk.
Did you already obliterate the other disk?
