I tried to install windows 7 on my brand new computer (finished building it today) but i need some kind of driver. I came so far in the windows installation so i can choose what language and region i live in and press start installation and then first thing i see is i need some kind of driver for cd/dvd but i am installing it from a USB flash that i have an ISO on it. Specs: CPU: 6600k, GPU gtx1080, Motherboard MSI Z170A PCMATE, harddrive seagate barracuda 2tb 7200rpm. Also i cannot see the harddrive when i press browse in the installation, the only thing i see is my usb. Please help!
