I promise, it is that easy. You need to boot ChromeOS by pressing CTRL-D *before* the black SeaBIOS screen appears. Then download and run the script. First set the boot options back to the default, then redo the dual boot setup. Hitting ESC on the SeaBIOS screen won't work because the stock SeaBIOS (which was reinstalled when you did the factory reset/recovery) is broken - not that it would help now, because you need to boot ChromeOS.
