It makes a difference. If you follow that approach, you will need a working usb drive as well.
In my opinion, it's best to start with a sneek only setup (without di) I had sd cards that weren't recognised if bootmii was installed as boot 2. In that case, you can power the wii
with the sd card removed, insert the sd card and launch bootmii from the homebrew channel.
If your sneek setup is working, you can copy your nand folders over to your usb drive and use those for a uneek setup as well. (you know they are fine)
If the uneek setup is working, you can add di and an fst extracted game in the games folder.
