I've used modmii to install homebrew and installed USB loader and USB loader GX, but now when I load up the channel, it asks for a hdd to be inserted in. I use a samsung M3 portable drive 500gb for this and I have used Wii backup manager to load the iso's onto the drive. I'm lost on what to do as I've tried reformatting the drive numerous times and at the moment it is in FAT file format. Prior to modmii, i was using a youtube guide to softmod the wii and at that time USB loader GX formatted and recognised the hdd. Now when I load up USB L GX, it just return to the wii menu screen. Can you help me please?
