So I installed a new hard drive however I do not have the original discs the only discs I have are to my 21in Imac is there anyway to install this without buying new discs or is there anyway to recover my old hard drive I think I deleted a folder I suppose to when I tried to restore so now I have 2 hard drive no OS and a macbook I can't use
