What procedure did you use to clone? There basically is
the "one" way, using dump + restore on partitions (not
slices!), or dd on either partitions, slices, or the
whole disk.

Images cannot be attached to list messages. :-(

You can use "echo *" in the loader stage, if I remember
correctly. Enter "?" for a list of the available loader
commands (or was it "help"?).

Good, so the copy you've created seems to be okay.

Maybe you just missed to prepare the "boot attributes" of the
new disk properly?

I suggest having a look at those documents:

Disk Setup On FreeBSD

Backup Options For FreeBSD

I'm almost sure that you will need to re-initialize something
within the boot chain (guess without further diagnostics)...
