My objective is to Mount C:\data\www to boot2docker VM image

From "Manually sharing directory as docker volume mounting point":

You need to:

• modify your VirtualBox VM (make sure it is stopped first):

  VBoxManage sharedfolder add <machine name/id> --name <mount_name> --hostpath <host_dir> --automount
  # in your case
  /c/Program\ Files/Oracle/VirtualBox/VBoxManage.exe sharedfolder add default --name www --hostpath 'C:\data\ww' --automount
  

• add an automount to your boot2docker VM:

  • Edit/create (as root) /mnt/sda1/var/lib/boot2docker/bootlocal.sh, (sda1 may be different for you)

  • Add

    mkdir -p <local_dir>
    mount -t vboxsf -o defaults,uid=`id -u docker`,gid=`id -g docker` <mount_name> <local_dir
    

(you might have to add the umask as in here)
