This article describes my steps to setup the iBash environment in my Windows 7 OS.

install virtual box

create a VM and install CentOS

• While installing, just select Linux, instead of Redhat
• Rember to select Desktop CentOS in one of the step, instead of using the default minimal CentOS, to use the GUI
• Install Enhance functions to the VM(Just click the menu item of the virtual box)
• Enable bi-directionaly Clipboard between VM and the Host OS.
• Specify a Share Folder to transfer to/from CentOS
