It can be installed with windows...
However...
I just finished my first installation of Linux (Redhat 7.2) and was up and running Gnome and KDE gui apps in about 4 hours...
I'll never go back...
The Install was easy and painless...
Now there is a learning curve... but it isn't THAT bad and the it comes complete with 2 gui office's also...
and some of them will READ .doc files and such...
DO IT .. all the way...dump windows and go for the gusto...
