There's your problem. Why would you do that? All you needed to do was remove any pirate channels you'd installed from menu and SD. i.e. wad games.uninstalled IOS35, IOS36, IOS60patched and
Failing to install bootmii, sadly, has just cost you either:-
a) The cost of a new Wii.
b) The cost of a repair of a Wii. (75USD-175+USD)
c) The postage when sending back under Warranty.
What you have done is removed the System Menu of your Wii and left yourself with no way of changing or replacing it. Bootmii/boot2 could have enabled you to install another copy.
