"A required device driver is missing..." Fresh install of Win 7 on new build.

[Arrofalcon]

I just put together my first build and I'm trying to install Windows 7 Pro on it.
I have an external USB solid state drive (298GB) that I put a Windows 7 ISO on with Rufus.
I went into the boot menu of my Gigabyte GA Z170 HD3 motherboard and selected the USB drive as the primary boot drive. I have two internal hard drives set to RAID 0.

I get to the windows splash screen and CANNOT get past the "Load Driver: A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now." "Note: If the Windows installation media is in the CD/DVD drive, you can safety remove it for this step."

I click "OK" and I get "No device drivers were found. Make sure that the installation media contains the correct drivers, and then click OK."

I tried every USB port (10 of them!) and NOTHING works...as you can understand I am a little frustrated after spending 4 hours building the computer and being stuck on this error for the last 5 hours....

I tried reformatting the USB drive several times and rewriting the ISO. I also tried re-downloading the ISO from the MS website with no luck...

I don't have an optical drive. I tried putting an ISO image of the motherboard driver disk on a separate USB with no luck.

Any help is very VERY appreciated.

Just use a normal usb 2.0 Flash memory(4GB or more) and use a Windows7-USB-DVD-tool software to create the booteable USB.
IF you have a USB2.0 port at your mobo use it in order to avoid that driver missing issues when installing windows.

I bought a new 8GB USB thumb drive today and tried the install again. SAME PROBLEM.
I created an ISO of the motherboard disk, but I don't know if it will do any good to install it on another USB and try to install it during the windows installation.
Am I missing something obvious here? This process should NOT be this difficult. It's just a driver; windows should auto-detect the USB anyway, otherwise it wouldn't boot into the windows screen to begin with!

I tried again using the Windows 7 USB tool from the Microsoft website. Still nothing. Same error about the driver.

Personally the thing i did, worked today!
I had the same problem but i had 1 hard disk drive than a raid 0 array.
I did the following steps:
1) i connected the formated hard disk where the windows would be installed to another pc so i could access it.
2) i downloaded motherboard's chipset drivers. It was 1 .exe file
3) i extracted the drivers to a folder called inf
4) i copied the folder to the formated disk
5) i put back the disk to the pc where i wanted to install windows
6) i booted via the usb flash drive and started windows setup
7) after i got the screen that was asking load driver... cd/dvd blah blah i pressed the button find and i pointed the inf folder on the disk.
8) after that it worked so i installed windows

PS if for any reason it this doesnt work for you you can try 2 things
1) attach a 3rd disk (non raid) with the folder inf as i mentioned above coz maybe the raid array wont be recognized by windows setup.
2) make a folder inf 2 and put the raid controler drivers there so the setup can access your raid controller.

sorry for my bad english. im greek thats why
i hope it works
