Please I want to upgrade my pc to win 7. Can anyone help me?
Boot with Window 7 Dvd. (window 7 RTM i.e build 7600 will be a better option)
Follow the installation prompt and select upgrade option. (Upgrade will take longer time cos ur system will be backed-up so that you will loose non of ur files)
But doing fresh installation for win 7 will be the best if you get appropriate drivers for ur hardware.***Tip: I discovered most Win XP drivers work perfectly with win 7, you may google it up anyway.
