Windows will install with it's own generic AHCI driver
Once installed you can then install the Gigabyte AHCI driver that you will find on your motherboard CD, or from download.
I had an annoying issue with my Asus rig when running the standard Windows 7 AHCI driver: my hard disks were showing up as removable devices. Installing the Asus AHCI driver corrected that problem.
There is an option to load drivers
during Windows installation, but obviously I did not do it. I don't know if it is necessary or of any benefit to do so beforehand. You could try it and let us know how it turns out!
To install the AHCI driver afterward:
- Open Device Manager
- Navigate to IDE/ATA/ATAPI Controller > ***AHCI Serial ATA Controller (or similar)
- Right click > Properties
- Choose: Update Driver
- Browse to the folder that contains the AHCI driver from Asus > Select > OK
- “Successful” Message > Close
- “Must Restart > Restart
- Drivers Install > Another Restart necessary > Restart
- Drivers successfully Installed. Remove Hardware Icon no longer showing.
