Well, that depends. Turn on your wii and see how many times the disc drive light flashes. Does it flash twice? Then you are lucky and can use this http://www.wiihacks.com/bricked-wii-...tion-here.html to fix it. If it doesn't, try holding reset when you turn it on. If priiloader comes up, you can fix it from within priiloader. If priiloader doesn't come up, you can only try the recovery menu. If that doesn't come up and have a NAND back-up or the keys of the wii, then you can ask a member here to flash your NAND.
