    What to do if my Biostar H81MHV3 Motherboard system doesn't boot from the hard disk drive?

      Sarah SingletonJul 29, 2025
      If your system doesn't boot from the hard disk drive but boots from the optical drive, check the cable running from the disk to the disk controller board, ensuring both ends are securely plugged in. Also, check the drive type in the standard CMOS setup. Backing up the hard drive is extremely important, as all hard disks are capable of breaking down at any time.
