I just downloaded Docker Toolbox for Windows 10 64-bit today. I'm going through the tutorial. I'm receiving the following error when trying to build an image using a Dockerfile.
Steps:
- Launched Docker Quickstart terminal.
 - testdocker after creating it.
 - Prepare Dockerfile as documented in "Build your own image" web link
 - ran the below command
 
    docker build -t docker-whale .
Error: $ docker build -t docker-whale .
unable to prepare context: unable to evaluate symlinks in Dockerfile path: GetFileAttributesEx C:\Users\Villanueva\Test\testdocker\Dockerfile: The system cannot find the file specified.
BTW: I tried several options mentioned @ https://github.com/docker/docker/issues/14339
