I have bought an updated MBP 13 i5". I took out the M4 256GB from early 2011 i7 and install to the new MBP... However, it shows a stop sign which it doesn't pass the startup screen. I pressed option to start and it shows my disk and recovery disk. However, both will shows a stop sign after i clicked on them. I also tried to use a bootable lion usb and a DVD to see if i can install a fresh system. Both doesn't work. Is this means my hard drive is dead? or anyway around to fix it?
