For many reasons, it can happen that deliberately or unintentionally BIOS settings are lost.

In order to restore normal start-up, here are the recommended changes:

- TIME (if different from the current one)

- DATE (if different from the current one)

- in the top menu select ADVANCE

- under SATA, change IDE to AHCI

- under Health set the fan speed as SMART FAN

- go to the top menu and select SAVE & EXIT to exit BIOS

At this point, if the data on the disk or the operating system are not damaged, the opeating system should be loaded on board.
