BootMii allows for backing up and restoring your Wii's NAND storage. This page will guide you in backing up your Wii's NAND to an SD Card, which you can then use however you like.
Family edition Wiis (Wiis without GameCube ports) CANNOT restore NAND backups. This is because of the lack of GameCube ports which are required on non-boot2 Wiis to enter the restoration confirmation code. Regardless, it is still recommended to make one on these consoles.
You need an **SD card** to use BootMii at all, but especially to create a NAND backup. If you do not have an SD card on hand right now, you can skip this page, but it is HIGHLY RECOMMENDED to return to this page later to back up your NAND.
Navigating BootMii is not possible using a Wii Remote. You must use the POWER and RESET buttons on your console, or a GameCube controller plugged into port 1. To navigate between options, press POWER on your Wii (or left/right on the +Control Pad on a GameCube controller). To select an option, press RESET on your Wii or A on your GameCube controller. You will NEED to use a GameCube controller to restore a NAND backup in the future if BootMii is installed as IOS.
If the screen stays black and the blue disc drive light is blinking upon launching BootMii, 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. After the previous step completes, BootMii will verify the backup. Ideally, all the blocks should be green after the verification process.
+ 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.
Two files will have been created on the root of your SD Card: `nand.bin` and `keys.bin`. `nand.bin` is your Wii's internal memory, while `keys.bin` are your console's keys.
Priiloader adds a secondary level of brick protection, and is highly recommended even if BootMii was installed as boot2. It is especially important for users of BootMii on IOS.
