How To Fix The Mac Mini Won't Boot With A Flashing Question Mark?

I've been having an issue with my late 2014 MacMini, which has been used as storage since 2016. Recently I wanted to trade it for a new iPad so I intended to format it for a macOS reinstallation. However, it works extremely slowly, I booted it into macOS Recovery Mode, and everything went well, however, it was stuck in the middle of the format. I did a hard reboot but the format still failed, responding with a flashing question mark. What should I do? Any suggestion would be appreciated!

Hi there, there are sorts of solutions to fix the flashing question mark given by your Mac device when it loads up:

1. Check Startup Disk System Preferences

2. Reselect the right startup disk in macOS Recovery mode

3. Repair the startup disk or Macintosh HD with Disk Utility

4. Format startup disk via Disk Utility and reinstall macOS

5. Check and replace the startup disk (HDD) cable

6. Update the firmware of your MacBook

7. Check the lifeboat connector on the logic board

8. Check the faulty SSD socket or hard drive on the Mac logic board

Worthwhile, if you have any important files on the Mac computer, you'd better recover files before you fix the question mark appearing when your Mac starts up.
