Ok first of all I apologize for being a noob. I haven't have had any problems with my macbook pro so not very familiar w/ recovery etc on a MAC. So my battery started not to charge....whenever I unpluged the power the macbook would instantly die...yeah not fun but wait for it... so I boot up and it is stuck on the white screen (apple/kernal) Now I assume that the os got corrupted when I lost power. This is a Snow Leopard OS. I can get to the disk boot but not sure what to do. Is there a way to copy the data of the hd? Can I restore the os w/ loosing date? Any help is greatly appreciated.
