well i updated to lion and it is pretty much buggy i knew this but its not stable for day to day use. basically i didnt back up snow leopard with anything and well then i formatted my hard drive with a windows disk so i could get it clear since i could not find disk utility's in the lion disk and then i tryed to load the snow leopard disk and then it would not boot so i could not re install snow leopard on my macbook pro please help!!!!!!!!!!!!!!!!!!!
