Have you looked in the Bios under Boot Manager to set your boot order? Have tried loading windows from a USB?

I don't understand what the problem is. It seems that you are running the Windows installation program (what version of Windows), but then the "program make me choice cd/dvd driver". What program is that? Is the Windows installer asking you to install a driver program from from an optical drive? There is no option to disable scanning for optical drives in your board's BIOS. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

oRau ... are you talking about "F6" during Windows Custom Install where you can load drivers for your hardware so the "Windows Install" can find them? As parsec is pointing out more information is required to help you. ------------- Z170 OC Formula Intel Core i7-6700K CPU 32GB DDR4 3200 NVIDIA GTX 970 Asus VN247 Monitor Samsung SSD 950 Pro 512GB WD 2TB Windows 7 Pro 64-bit Windows 10 Pro on VMware |

Yes, one of the 1st stage of installation its the question to me to choice a driver for cd/dvd. Installing W7 x64.
No, its automatic process to asking me for a drive for cd/dvd, i cant ignore him (except in cases when the installation program does not find the cd/dvd). |

Now I know what the problem is, installing Windows 7 on a Skylake system. The problem is Skylake boards, like a Z170 Extreme4, require a USB 3.0 driver to be available from the OS installer, or NONE of the USB ports will work. That is true for a Skylake board from ANY and ALL mother board manufactures. Intel's design of the Skylake chipsets is the cause of this problem. Windows 7 does not have a USB 3.0 driver included with it, and the Win 7 installer is asking for a USB 3.0 driver. The installer program is not smart enough to tell us this, all it knows is it needs a driver, since you are using a USB flash drive to install Windows 7. Since the USB ports will not work, it wants you to use an optical drive. ASRock knows about this situation, which is described in your board's manual. ASRock also provides a couple ways to deal with this situation. The following is from your board's manual: ________________________________________________________________________ Enabling USB Ports for Windows® 7 Installation Intel® Braswell and Skylake has removed their support for the Enhanced Host Controller Interface (EHCI - USB2.0) and only kept the extensible Host Controller Interface (XHCI - USB3.0). Due to that fact that XHCI is not included in the Windows 7 inbox drivers, users may find it difficult to install Windows 7 operating system because the USB ports on their motherboard won't work. In order for the USB ports to function properly, please create a Windows® 7 installation disk with the Intel® USB 3.0 extensible Host Controller (xHCI) drivers packed into the ISO file. Requirements A Windows® 7 installation disk or USB drive USB 3.0 drivers (included in the ASRock Support CD or website) A Windows® PC Win7 USB Patcher (included in the ASRock Support CD or website) Scenarios You have an ODD and PS/2 ports: If there is an optical disc drive, PS/2 ports and PS/2 Keyboard or mouse on your computer, you can skip the instructions below and go ahead to install Windows® 7 OS. You only have an ODD (For Intel Skylake platforms only): If there is an optical disc drive but no PS/2 ports on your computer, please enable the PS/2 Simulator option in UEFI SETUP UTILITY > Advanced > USB Configuration, which allows the USB port to function as a PS/2 port, and then you can install the Windows® 7 OS. Please set PS/2 Simulator back to disabled after the installation. You've got nothing: If you do not have an optical disc drive, please find another computer and follow the instructions below to create a new ISO file with the Win7 USB Patcher Then use the new patched Windows® 7 installation USB drive to install Windows® 7 OS. ____________________________________________________________ The instructions, and this explanation, are found in section 3.4 of your board's manual. You can get a copy to view with a pdf file reader here: http://www.asrock.com/mb/Intel/Z170%20Extreme4/?cat=Manual" rel="nofollow - http://www.asrock.com/mb/Intel/Z170%20Extreme4/?cat=Manual The Windows 7 USB patcher program can be found here, at the very bottom of the page: http://www.asrock.com/mb/Intel/Z170%20Extreme4/?cat=Download&os=Win764" rel="nofollow - http://www.asrock.com/mb/Intel/Z170%20Extreme4/?cat=Download&os=Win764 You are in the You've got nothing situation. Your only option is to use the Windows 7 USB patcher program to add the USB 3.0 driver to the Win 7 ISO installation media you are using. ------------- http://valid.x86.fr/48rujh" rel="nofollow">
