Booting OS-9 from a directory on the hard drive will only work if OS-9 is 
already installed on the hard drive in the first half of the drive.

I think the instructions included with my RGBDOS package explain how one would 
install OS-9/NitrOS-9 on a .vhd disk. You will certainly need to boot 
OS-9/NitrOS-9 from a floppy, create a new boot disk that includes the .vhd 
driver package, boot from that new floppy, and then format the .vhd drive for OS-9.

You should not use more that $5A000 sectors for OS-9 on the .vhd image or you 
will overlap the Disk Basic partition.

This creation can be difficult if you are new to OS-9. A formatted .vhd image 
can be found on the VCC site which has an older version of NitrOS-9 installed. 
I'm not sure which directory Joseph put the boot disk on, 255 or 254.

Have you been able to boot from the floppy? If not there is a problem with the 
nightly build.
