converting disk from native to fat

[steivor]

I'm an absolute newbie in Linux. I tried to install it on my pc and in a way it works fine. The thing is that I have a program I'm fond of that only runs under windows. What happend when i got Linux was that all my harddrive became Linux native and I don't know how to make my 20 mb fat partition that for some reason is left bigger f.eks like a giga. I downloaded a program called fsresize and in the readme file it said that i should write make logged on as an ordinary user and afterwards write make install logged on as root. I do this, but very many lines with something that look like errormessages occur at the first step and at the other step i'm told that it cannot find the install. So now I wonder: how do I install some program in Linux with Gnome or KDE? Or: Where shall I stand in the filesystem when I shall write the commandoes "make" and "make install" and is there something else I should do first? Please help me somebody cause my family is starting to get desperat. Yours faithfully Ingrid Chatrine Schrøder.
