I would recommend a 4GB drive, as the Windows DVD ISO is 2.35GBįirst we’re going to open up diskpart to prepare the Flash Disk. The N270 ATOM processor does not support x86_64 (amd64) extensions, so you’re going to want to grab the 32bit version. Your Free for One Year Windows 7 Key and Release Client DVD-ISO can be downloaded from here: This guide will tell you how to acquire Windows 7, prepare a flash drive to install Windows 7, and to acquire the necessary drivers after installation is finished. I figured this would be a good time to make a guide specifically for you in the same situation as I was. I saw a few incomplete guides out there, including the one that I used to install Windows 7 on my eee PC 1000.
