I'll be happy to help assist you with this. If you see a flashing question mark on your Mac's screen at startup, it means your Mac can't find its system software. Please try the steps in this support article: If a flashing question mark appears when you start your Mac . Let me know if you have any questions. Regards. Show more Less Reply Link
