open barry allen plugin then scroll down to wizard for images at MB_Images and press ok then select number 2 and that will extract and install the image when its finished it will reboot.
go back to barry allen and choose wizard for installed images and press ok,then select number 3 and choose your image and press ok.
i am using barry allen 5.2.7 if its not installed and you have an hard drive fitted disconnect it,make sure your usb is in at the back and reinstall it through TSPanel.
