My 2011 Macbook Pro won't get past the Apple loading screen with the spinning. I've tried restting the PRAM & SMC and still have the problem. When I try to boot the install disc nothing happens, and when I try selecting it using the option key, it just freezes. Also when I try to use Lion recovery, it freezes as well. I know it's not the harddrive, because my windows partition works perfectly and still experienced the problem when I swapped the harddrive out with another one. The one thing I haven't tried is hooking it up to my other mac via Firewire through Target disk mode. The problem is I can't access Target disk mode. When I hold down T at startup to get it running, nothing happens and it just goes to the apple loading screen again. Any other suggestions?
