Strangely I cannot find the error message text you presented. Is this
a check from the FreeBSD live system? Which OS version?

How has the disk been initialized (MBR or GPT or ZFS)?

What exactly did you do (example of commands)?

But it looks like this (given the few informations above):

There are two steps to do: First is to re-initalize the boot block
of the disk (boot0cfg, maybe fdisk -BI), and the partition has to
be successfully (!) fsck'd and marked clean (fsck -f).
