  1. If these drives were already formatted then you likely just need to download and install the proper SATA driver from the motherboard support site.

    If they are new drives you may also have to add them through Disk Management.
  2. I can access all the drives in windows just fine, my problem is when I load the windows install from the DVD, it only shows the 2 drives, the drive I want to put win8.1 on isn't listed

    In order to detect devices on additional storage controllers, drivers may need to be loaded during Windows Setup. When you encounter the Where do you want to install Windows? component of Windows Setup a button labeled Load Drivers will be present in the lower left corner of the window. This button will initiate search of USB or optical media for the basic drivers required to see additional drives. The EVGA Z77 FTW appears to have a secondary Marvel SATA 6Gbps driver for an additional two ports above the Intel Z77 two ports. The driver for this is listed as “Sata 6” at the EVGA download center. Unzip this driver to a USB stick or external drive and use the Load Driver button to select it during Windows Setup. Alternatively, you could ensure that the operating system drives for both operating systems are connected to the ports provided by the Intel Z77 chipset.

    For more advanced users including system administrators and IT pros drivers can be added to customized Windows installation media using deployment technologies available from Microsoft. For example, they can be quickly added to a deployment share in the Microsoft Deployment Toolkit (MDT) and made available on all media generated by MDT. Through this process, installation media created through MDT can be used to install a base image with customized driver support and applications across an entire organization of varying configurations and requirements.

    Intel's SATA controller is much better than Marvell's so attach the most important drives to the Intel controller.

    Just out of curiosity, why do you dual-boot W7 and W8.1?
  6. I bought W7 but want to try Win8.1 and if I don't like it then I have W7 still installed
  7. so figured I would buy Win8.1 and just dual boot
  8. also I keep my SSD and my d drive on Intels, for some odd reason it wont let me edit my post
  9. I have Win8 on my laptop but I don't know if I can get the free update since the laptop came with Win8, anyone else having a problem with editing their post?
  10. Hi,

    1) Windows 8.1 is a free update to anyone with Windows 8. It's accessed from the Store. The initial download is 3.5GB.

    2) Windows 8.1 isn't that different from Windows 8, but then I use START8 anyway to keep the Desktop.

    3) I don't see the point in spending $100 on Windows 8 to dual-boot with your existing Windows 7. You already have W8 to play with, performance is basically identical and it's no fun managing two basically identical Operating Systems anyway (you'll just end up not using one).
