Things to download:
- The latest version of CFG loader
First thing to choose is the way you format your hard drive. You have four options, WBFS, FAT, NTFS and ext. I will explain these for a bit.
WBFS was the first format supported by the USB loaders. This filesystem is quite outdated and has some instabilities when deleting games. When you format your HDD this way you can only use it for storing Wii games, nothing else. I don't recommend this filesystem.
This is the most flexible format. You can store Wii games and other files on it and it is supported by every OS. Minor drawback is the 4GB filesize limit. You won't encounter problems when installing games as the loader automatically splits and/or scrubs them. When formatting your drive in FAT you should use an external tool like GParted because Windows won't create a large enough drive.
NTFS is mostly used when having large drives. Not every OS supports this format and CFG has some case sensitivity problems on NTFS. When using one you need to add several lines to config.txt or meta.xml or use the tool supplied. More info on how to do this on the end.
Ext covers ext2, ext3 and ext4. Ext support is quite new and therefore can have bugs. Currently ext is read-only, so you can't install games via USB loaders.
My recommended choice is NTFS but it all depends on what you like.
To start unzip the package to your SD card so you end up with x:/usb-loader and x:/apps/USBLoader/boot.dol
