      If your Biostar Motherboard system isn't booting from the hard disk drive but works fine with the optical drive, first check the cable that connects the disk to the disk controller board. Ensure both ends are securely plugged in. Also, verify the drive type in the standard CMOS setup. It's also important to remember to back up your hard drive, as hard disks can fail at any time.

      If your Biostar Motherboard system only boots from the optical drive, and you can read hard disks and use applications but the system fails to boot from the hard disk, back up your data and application files. Then, reformat the hard drive and reinstall applications and data using backup disks.
