If savemiifrii is not working you will not be able to use an autoboot disk. You don't have preloader as it is overwriten with the system menu install. How about bootmii as boot2. When you boot the wii, does the blue led flash 1 or 2 times? Two times would mean bootmii boot2 and could be used to restore your wii. Otherwise there is nothing you can do.
What wad did you delete and why? You know for future reference you should never ever ever delete any ios under 200, or your system menu wad.
