You have to set up SD card , this is in the BootMii ... menu as "prepare SD card" you need to run that before you launch BootMi , it creates 3 files in the BootMii folder Which is what's the new thread is about my problem as i had the same one, though , i prepared SD card and it failed because of a bad SD card, specifically the adapter for micro sd cards.by Stewox - BootMii Beta
