Hey people I am having problems on Asus EeePC 1225B installing Windows 7 Ultimate. Says Cannot find device drivers after entering the setup, I even tried external dvd-rom says same thing on a flash drive
Windows comes with many device drivers but not all. The most common that would affect install are those that support SSDs or certain RAID settings for a hard drive. So you could try changing the RAID settings in your BIOS or you will need to load drivers. See Microsoft Community.
So what I did was plugin the usb stick into the usb port 2.0 and it worked. If you want to install windows 7 ultimate on usb 3.0 buy a usb 3.0 16 gb stick
