Last night I applied EFI Firmware update 1.8 to my Macbook (late 2008). After installing EFI Firmware Update and rebooted my computer and installed SuperDrive Firmware Update 3.0. After that my Macbook rebooted and a black screen is showing with "No bootable device. Please insert bootable device and press any key to continue". I put in one of the bootable installation disck (MAC OS) and it's still stuck on the same screen. I have also tried restarting my macbook manually but no luck. Have anyone experienced that?
