ok i gave you a step ahead of this, sorry. the reason why the nand1 folder has the pl-us,(pl=postloader) an depending on what channel you are using to boot to uneek.(the one with the banjo music, that also give you text will not work.) they are two differnet set ups an boot different ways. to use the postloader nand, you'll need one of the neek2o channels, they can befound on the google code page, or here on gbatemp, in the neek2o channel thread. just leave the 1 game you have set up the way you have it. just rename your nand back to pl-us, an grab one of those channels an it should boot. might take a min, an will go black for like a min. but will show up, an you'll need to set up the nand just as you did when you first got the wii..I put the SD stuff on my 1gb SD card and renamed bootmiisneek folder. Then I put all the USB stuff on the fat32 partition of my USB drive (I have two partitions a fat32 set to primary and active and an NTFS with my games kept in a wbfs folder). Now intially I had my nand stored in a folder labeled pl_us and that folder was inside a folder labeled nands which was stored on the root of the fat32. I renamed the pl_us folder to just nand1. Also I read somewhere you needed at least one game on the fat32 parition in order for this to work so I took one of my .iso games from my NTFS partition converted it to .wbfs and stuck it in the root of the wbfs folder I created on the root of my fat32 partition. Despite all this it won't boot. My screen stays blank and after a short period the Wii drive will just start blinking. Also I even considered that possibility that my hard drive might be slow to start up even though I've never had issues with it before so I even tried booting to bootmii from HBC and still same result. Blank screen with flashing disc drive.
