Are you trying to install Windows? You don't need a driver for the hard-drive, you need it for the chipset on the motherboard so the Windows setup can detect the devices attached to the motherboard. That AHCI thing you are talking about is change in the BIOS you can do so Windows detects the drive, set the disk mode from AHCI to ATA (it may be called Legacy in some BIOSes), then it should see the disk to install it.
