That syntax isn't right. See boot.cfg(5) for examples.

It would because fdisk should be given disk names, not wedges. Run
`sysctl hw.disknames' to get a list of disk names (omit any dk*).

How did you manage to create a disklabel on a GPT partitioned (and UEFI booted)
system? It's a bit of a circus to do this. Can you show the output of:

```
sysctl machdep.bootmethod
fdisk wd0		# or, sd0, ld0, wd1, ...
gpt show wd0		#       "
```

-RVP

PS. if any of the GPT partitions have a `bootme' attribute, just get rid of it.
