The condition of this fault is that the system can normally recognize the hard disk. If the system cannot recognize the hard disk, users can refer to the content above for troubleshooting. "The system cannot boot from the hard drive" usually relates to the system power supply, BIOS settings, motherboard, IDE interface, etc. Users can first carefully check all the BIOS settings and see if the hard disk information in STANDARD CMOS SETUP is accurate. Users can use AUTO DETECT to automatically detect the hard disk settings.
If the hard disk cannot boot due to a power supply fault, it generally will not be able to boot from a CD either. To confirm whether it's a power supply fault, it’s best to try replacing the power supply. If the power supply is normal, further checks on the motherboard can be carried out. To determine the scope of the fault, try booting from a CD to see if it succeeds. If the CD boots successfully, it indicates that the problem may lie with the hard disk interface, where you can check if the IDE slot contact is good.
If the CD cannot boot either, it suggests that the problem may be in the motherboard control circuit or control chip. At this point, an external disk interface adapter card, such as a multifunction card, can be tried. However, before using the multifunction card, the CMOS parameters must be modified to disable the use of the motherboard's (NO BOARD) IDE interface by setting these items to "Disabled". If after all these diagnostics it still doesn't work, the only option left is to try replacing the motherboard.
