Try reading through the site rules again. You will see that linking to external guides are not allowed (usually because most of them suck, as you found out that yours did, otherwise you wouldn't be here).
See the Softmod Any Wii guide linked in my signature. Do not format, uninstall, or delete anything. Just follow the guide and mod your system on top of however you have it now.
GC BackupLauncher isn't really current either. If you are trying to use Dios Mios, we have a guide for that too. The three USB Loaders that you get in chapter 3 of Softmod Any Wii will work with DM as well. Devolution is also an option to get GameCube games to run off of USB. Others are more versed in that one than DM, but DM is what I use.
Links to DM, Devoultion, and USB Loader links all exist in my signature.
And don't try to do things "quickly". That's what causes problems and bricks. Take your time, read everything thrice before you do anything, and do the right thing the first time.
