###Initial installation and configuration Install Git for Windows which includes Git Bash.
Install VirtualBox and Vagrant.
Note: These fixes were not originally done for VirtualBox 5.0 and Vagrant 1.7.4. They are for the previous versions instead: VirtualBox 4.3.30 and Vagrant 1.7.3. Some of these fixes may not be needed now. For example, I recently upgraded to VirtualBox 5.0 and Vagrant 1.7.4 and I did not have to alter the Vagrant ruby (.rb) files as shown in part of this Gist below. I'll soon try from a fresh install (not upgrade) and update this Gist accordingly.
In Git Bash (always run as administrator), type cd ~
