Today, I'm creating this tutorial because I know some people (myself included) who run into problems when installing an update or uninstalling BootMii.
If you have a CiosPack installed on your Wii you won't be able to uninstall or reinstall BootMii without running into a rather annoying message like this one:
Image unavailable (removed by its host)
Today there's a solution. The problem is caused by an installed cIOS and for various security reasons, Bootmii won't install.
In this tutorial, I'll explain how to get rid of this message so you can reinstall Bootmii or uninstall it

Let's get started 
I. Preparing the SD card:
1. Creating the "Wad" file: (if it's already done, skip this little step)
- Open your SD card (on the computer of course
)- Create a new folder at the root
- Rename it "Wad". And there you go! The first step is done

2. Download IOS 36 v1042 with NUS Downloader:
- First of all, once you've downloaded NUS Downloader, extract the archive into a "NUSD" folder (this name isn't mandatory) where only the extracted elements will be inside
- Run "NUSD_13Beta.exe"

- Follow the path: "Data base --> IOS --> 0000000100000024 --> v1042"

- Check the boxes "local files", "Delete Content" and "Pack -> WAD"

- Click on "Start NUS Download" and just wait patiently while it loads!

- Once loading is finished, go back into the "NUSD" file (if you named it that) and a new folder "0000000100000024v1042" (I think) has just appeared, open it then copy the file "IOS36-64-v1042.wad"

- Put the file in the "Wad" folder created earlier! That's how the second step ends!

3. cIOS 36 from CiosPack:
- Once you've downloaded the Cios Pack from boardeur's tutorial, open the "corpv3.6M" file
- Copy the file "cIOS36-v3094-v3.6.wad"

- And finally put it in the Wad file

And your SD card is finally ready!
II. Reinstalling Bootmii on your Wii:
1. GUI Wad Manager:
- Insert your card into the Wii's slot
- Launch the HBC, then GUI Wad Manager
- Select "Browser --> Wad --> IOS36-64-v1042.wad"
- Wait while it loads, once done "OK --> Go Back --> Go back --> HBC"
2. Hackmii Installer:
- And there, once these steps are done, the message no longer appears!
And it's up to you what you set (uninstall, install, HBC, Boot2, Boot IOS etc)
- Once done, press the "home" button several times to go back to the system menu
3. Putting cIOS 36 back:
- Launch the HBC, then GUI Wad Manager
- Select "Browser --> Wad --> cIOS36-v3094-v3.6.wad"
- Wait while it loads, once done "OK --> Go Back --> Go back --> Wii Menu"
AND THERE YOU GO! Done
and you can repeat this procedure as many times as you want! So if you're tired of your boot2, do this and install boot IOS and uninstall boot2 That's how this tutorial ends! Have a good day and see you next time in a new episode of "today's useless homebrew"! (AD)!
