When i turn my Wii on the gray BootMii screen pops up and i have to use the Wii buttons to get away from it. Any help would be appreciated, THANKS
Bootmii as boot2 loads when it finds three specific files in a folder called bootmii on your sd card when you power on your wii. To stop this, try powering on without your sd card inserted into your wii.
Or you can backup the bootmii folder safely on your pc.
