A question mark on the grey screen of your MacBook Pro indicates that the system cannot find a valid startup disk. This may occur due to various reasons, such as a corrupted operating system, a failed hard drive, or incorrectly configured startup disk settings. To resolve this, you can try resetting the NVRAM/PRAM, booting into Recovery Mode to repair the disk, or checking your startup disk settings in System Preferences. If the issue persists, it may require professional assistance or a hardware check.
