    If the `Launch BootMii` button does not appear, please [re-launch the HackMii Installer](hackmii) and install BootMii.
    {: .notice--warning}

    If the screen stays black and the blue disc drive light is blinking, you are missing the BootMii files on your SD card. Download [this zip file](https://static.hackmii.com/bootmii_sd_files.zip) and extract it to the root of your SD card, then try again.

1. You should see an image similar to the below now on your screen:

1. NANDバックアップが開始します。 進行状況は画面に表示されます。
    + "Bad Blocks" are normal. NANDバックアップでいくつか表示されても問題はありません。

1. After this step, it will verify the backup. 確認が終わった後に全てのブロックが緑色になっていることが望ましいです。
    + If you have factory bad blocks with uncorrectable pages, these blocks may fail to verify. As long all non-bad blocks are successfully verified, this should be fine.

1. To exit BootMii, press the Back button (the one with the arrow) and then you can press either the Wii Menu button or the Homebrew Channel button to exit where you want to.

<div id="restore-notice" class="notice" markdown="1">
Please be reminded that <strong>restoring a NAND backup is usually a last resort,</strong> and that there often better ways to fix your brick. There are often better ways to unbrick your console.
[ブリックの原因を特定](bricks)し、その問題を解決することに注力してください。
To restore from a NAND backup on your SD card, you can follow the instructions for [RestoreMii](bootmiirecover). **Family edition Wiis (Wiis without GameCube ports) CANNOT restore NAND backups.**
</div>

BootMii as boot2 is recommended, but only available to install on early Wii consoles. Otherwise, it can only be installed as an IOS. If you would like to change this, you can use the app [BootMii Config Editor](https://oscwii.org/library/app/BootMiiConfigurationEditor). Or, you can edit `sd:/bootmii/bootmii.ini` manually.
{: .notice--info}

To make sure you don’t lose the files, it's recommended to copy `nand.bin` and `keys.bin` from the root of your SD card to your computer. `nand.bin` is a backup of your console's internal memory, while `keys.bin` are your console's keys.

[Continue to Priiloader Installation](priiloader)<br> Priiloader adds a level of brick protection, and is highly recommended, especially if you were only able to install BootMii as IOS. IOSでしかBootMiiを導入できなかった場合は、必ず導入してください。
