Thanks again for your help, everyone. I previously asked a couple of questions that some staff answered for me, thanks! Now I believe I am ready to begin updating my wii, but I am a bit confused about where the Softmod ANY Wii says: "Remove all GC controllers, GC memory cards, USB devices." I presume GC means "Gamecube"? If the modifications to the SD card on being done on my PC, I presume then that this means these devices should be removed from the Wii when executing the files that have been installed on the SD card from the Wii? Just to make sure I understand, I currently have the external USB hard drive installed, a couple of memory cards, and that is all. All of these things should be removed while installing the files on the SD card? Sorry if this seems like a dumb question, I am very new at this. Thanks!
The HackMii installer will often fail if these devices are not removed. I know when I first modded my system 3 or 4 years go, it failed for this exact reason. Once you are done with HackMii, you can start plugging things back in.
