This is the way that I use always to develop anything on Windows.
Start downloading Vagrant and VirtualBox:
Install VirtualBox and Vagrant using the default options.
After reboot, create a folder where you will host all your projects.
I already have one, where is everything. Even if I format the Windows, that folder is intact and is just reinstall everything and resume the work where I stopped.
Open a command window and go to the folder where your projects will be. Write this command:
Edit the file called Vagrantfile without any extension.
Edit this line inside the file:
config.vm.box = "base"
change it to:
config.vm.box = "jadesystems/rails5"
Save the file.
We will use a ready vagrant image from here: https://github.com/lcreid/rails-5-jade
On the command write this command:
And wait, it will download the files necessary.
Now follow the instructions on the github page from the vagrant image: https://github.com/lcreid/rails-5-jade
