Hacking Cant install BootMii

[DragonRider]

Hello, i got a old wii yesterday and want to run homebrew and backups on it.

i tried this tutorial (http://gbatemp.net/threads/how-to-s...backup-wii-gamecube-and-wiiware-games.360687/) but have the problem that i cant install Bootmii.
It tells me "the installed boot1 version prevents a boot2 install (-2)"
I also tried to install it as iOS (I dont know atm. what dies mean exactly) but i also get a error at this.


I am realy a noob with the wii, but is there a other way or a other tutorial i can follow to make Nand Backups and get Backups running on my wii?

You don't really need a NAND backup if you use ModMii.
It generates a tutorial for you and is much much more easier then installing everything manually.
