Wont boot after running out of power
Yesterday my MacBook ran out of power, and when I restart the computer it just shows a grey background with a apple and the spinning wheel and a progress bar, when it has been running for a minute it automatically shuts down. I have tried resetting the rams, and tried resetting the efi firmware. But no luck. When I insert the installation disc it just freeze with the apple logo. I suspect that it has been trying to update firmware when closing down, but not sure. I also tried to insert a restoration of efi 1.9 disc, but wont accept it. Does anyone have an idea?
