i just got a 2006 macbook pro with snow leopard. and i have a macpro 2006 with lion. long story short i decided to erase the macbook HD and clone from my macpro o put lion on it. when ive ever had problems with one of my HD on my macpro i just erase that hd and clone from my second hd, i keep one of my internal hd,s for backup. that solution has never failed me. well after i cloned from my desktop to my macbook and restarted my macbook all i get is a grey screen with a circle and a line in it. if i restart it holding the T key it shows up on my macpro and when i check the hd it looks like everything is in there. what have i done wrong.
