doesnt boot when restart the laptop
I bought an old macbook pro 17 inch a1297 and later found that it did not have hard drive. So I installed a new blank hdd n somehow installed mountain lion through bootable usb.laptop works fine but with a boot problem. I always have to disconnect the battery connector from the board and reconnect to get it worked. If I do not do this, laptop just hangs at startup tone. Please help. I will be very grateful.
Es esta una buena pregunta?
