You can face two different scenarios :

Step 1: Go to Apple menu > System Preferences > Startup Disk.
Step 2: Click the Startup Disk icon that is generally labelled as Macintosh HD.
Step 3: Click Restart and the Macbook pro flashing folder with the question mark at start-up should be solved on your Mac.
- However, on the other hand, if file folder with the dreaded question mark is displayed and the system is not continuing with the boot process.
