Wii Problems

Jan 29, 2011 at 9:05 AM

I recently bought a wii nintendo system at Christmas and have had no problems  but now when you turn it on and go to USB loader all it says is No WBFS or fat/NTFS partition found you need to select or format partition and then it has 3 buttons Select, Format, and Return. I need to know what to do and if I do it will it erase all the games. Thank-you Hoping to hear a reply soon
