What happens it you don't autoboot into Priiloader?

Wad Install Error Most likely have a cIOS installed incorrectly, out of date, or missing. If a file was needed, then it was not in the correct folder. If you are using cios38rev14 installer, put ios38-64-3610.wad file in the root of the SD card. Each programm needs its files in specific folders, so pay attention to that. Can also be a bad wad or not enough space on the Wii. Possibly formatted the SD card incorrectly.
