What should I do if I can't enter the system?

1. After the power is turned on, directly enter the BIOS interface (left picture) or enter (right picture) interface, the hard disk is not recognized, and it can be determined that the hard disk is faulty.

2. If there is another interface after booting into the (left picture), there is another possibility that the motherboard SATA port is damaged and the motherboard needs to be replaced.
