i’ve been asked a few times how to install windows 7 onto a netbook and i believe these are the minimum requirements:

1. format the usb stick (for example e:) within windows from a command prompt using the following command:
format e: /fs:ntfs /q

2.  from the command prompt window, change directories to your windows 7 dvd (for example d:) and type the following commands: 
d:
cd boot
bootsect /nt60 e:

3.  copy the entire dvd contents to the usbstick (you can use windows explorer for this)

i’ve read a lot of how to posts on the internet and many of these seem to have additional directions, tools or suggestions none of which were required on the sticks i have purchased.
