save your nand.bin and key.bin along with your bootmii folder to your pc
If your loaders depend on your sd card, (if you launch them with HBC) then only keep those needed files on your card
I have hacked my Wii to 4.3. Everything works fine except for the booting. It boots into the Multi-Mod Manager 1st. Any Idea what I did wrong?
That was it. Thanks a bunch.
