Solution: If you encounter this kind of error, you can still enter the system normally if you press Ctrl+Alt+Del to restart. After backing up important personal data to the hard disk, you can restore or reinstall the system and try it out. If it fails, it is recommended to make an appointment for hard disk maintenance and testing. If you can't access the system, you need to contact the service station to see if there is any important data to rescue the data (data recovery will involve costs).
