First enter the BIOS of the motherboard to reply to the default, F10 is saved, and then settled again. If it is invalid, it is recommended to get the merchant, what can you ask. There may be problems with the controller of the motherboard.

There are many reasons that cause this problem:

1. Check whether there is a soft disk in the soft drive, and then enter the BIOS, and turn off the A disk to close the A disk in the start order.

2. The "anti -virus protection" in the BIOS settings is enabled. If this is the reason, enter the BIOS and close the "anti -virus protection".

4. There is a problem with the hard disk. The problem is generally on the hard disk connection and hard disk bad sectors. If it is on the connection line, unplug the connection line, remove the dust on the top and the dust on the hard disk, and then insert it back or replace the connection line to solve it.

5. Re -partition with FDISK (data will be cleared, use cautiously.)

6. The fourth possibility is the most likely. It is recommended to try it first.

The prompt at the time of failure is "A DISK Read Error Occured Press Ctrl+Alt+Alt To Restart". I used the "fdisk/MBR" as mentioned above. It seemed useless. Later The mode of the hard disk is changed from "Standard Mode to" Enhanced
