Any particular reason to why? In all reality you are safer with a soft modded wii than you are without. Just dont play with things and follow guides until you know what the apps do.
And please, for the love of god (not as if I believe), make a nand backup with bootmii before you go and start doing things to "virginize" your wii, especially without fully knowing what is happening behind the scenes.
There have been quite a few people recently that have tried "virginizing" their wii and either by user err0r or faulty/old guide have managed to screw up their wii and did the complete opposite of what they wanted to accomplish. Thats why I say make a nand backup, even if you can only install bootmii as an IOS.
At least no matter how bad a wii gets screwed up, as long as I can get the nand backup or keys I can fix someones wii (ignoring the fact of hardware failure which is rare with the wii compared to ps3 and xbox 360 (and hell sometimes I can fix hardware failure too)).
