To use "Big Bang" you must be in flash image (not in a universe eg Ghost)
Big Bang will erase all universes present on your usb device
Then if you press red button, you will recreate brand new universes with same settings you already have in your flash image.
If you want a "mini big bang" (delete just ONE universe, you must use telnet and manually erase the folder containing the universe you want to delete.
