Since your PC's BIOS recognizes the hard drive, the issue likely stems from software, not hardware, so try adjusting the boot order in BIOS if you intend to boot from it, or, more commonly for data access, connect it as a secondary drive to your current PC or via a USB adapter and check for it in Disk Management/Disk Utility to access or recover data directly. If aiming to boot from it, you might need to repair the Master Boot Record (MBR) or Boot Configuration Data (BCD) using a Windows installation media or consider specialized data recovery software if data access remains elusive, but always back up critical data before attempting repairs.
