Hello good people
i am trying to format my master hard disk in command prompt(it is the only one on my netbook anyway). After formatting i would like to instal windows 7 starter on it. Could any one please provide some help. Even a link to a nice tutorial would do. thnxWindows 7 is often installed from a bookable DVD.
Bit installation over a network can be more INVOLVED. Whenever  there are many DESKTOP PCs to RECEIVE Windows 7 in a COMMERCIAL nor campus environment, special tools are put in PLACE on the network server.
