Do you have ocarina enabled? Some of the hook-types causes the game to blackscreen.
screen, no sound
no, i dont have ocarina on. (yet, i will when i know how to get the no timelimit code work)
tried to run it with ocarina on and se if that worked, but no luck. black screen no sound.
How big is the iso before you transfer it to your USB drive? Because I had the same error and it was caused by a corrupt iso.
For me 7zip didn't extract it completely and gave me an iso of about 400MBe problem, while it's supposed to be a 4.3GB iso. In that case you should extract the zip with Winrar or download it from another source.
If the size of the iso is correct however, I don't know what the problem could be.
In any case, it might be wise to check if the iso works with the Dolphin emulator (then you'll know the iso is not the problem at least).
