Motherboard: ASUS z170-a

I have just put together my first build and I am attempting to install Windows 7 Home Premium x64 via USB. Right after I click the install button it gives me the message that a required CD/DVD driver is missing. I have read support threads everywhere on the internet about this issue but am unable to solve it. I have no optical drive on my PC, and it is suggested that the actual problem is that it needs SATA drivers.

The screen allows me to browse the computer for the files, but it isn't recognizing any hard drive or USB device other than the BOOT device that has the Windows installation even after unchecking the box that only displays compatible drivers. I've attempted to copy the drivers from my motherboard installation DVD and place it on the USB drive that has the Windows install files but I can't locate them. When I enter the USB on my laptop and use file explorer to browse the drive, the folder setup is very different than on my build when I browse the device. I also have an external Hard drive that I attempted to copy the drivers to but the Windows installation screen doesn't show it. I can confirm from the BIOS that all of these drives are operating correctly and all USB ports are functioning.

One solution I have seen suggested online is to use USB 2.0 instead of USB 3.0, but I don't see any option for this in my BIOS if there is one. I do have something called "Legacy USB Support" enabled. My motherboard settings are all on the default settings. Any help would be greatly appreciated. :blush:

When Windows is asking for driver, just click Cancel. You will be brought back to the welcome screen. At the welcome screen, remove your USB drive, insert it back to DIFFERENT USB PORT. Click Install Now again. The installation process will be like usual.

Did not work :sad:

I am noticing now that it appears that when it starts up it is gathering all the Windows data from the USB drive into a BOOT <X:> drive as it still shows up even when I remove the USB drive completely. It won't detect it independently in another port, and doesn't recognize any of the hard drives on this screen either. I'm not sure what else to try.
