Boot order and finish - How to install Windows 7 on a netbook
Nearly there... before booting up the Lenovo S10 (or any other netbook), you will need to change its boot order, by going into the BIOS menu. Your NetBook will display instructions on how to start the BIOS menu when you switch it on. There should be an option to change which discs the netbook uses to boot-up. You may need to change the boot order so that your netbook boots up from the USB memory stick first. If it all works the Windows 7 installation program will start.
