make sure windows XP is installed first. THen install Linux Fedora.
When Fedora is installing u will get a choice where to install it. Just create 2 partitions one for the fedora OS (10gig+) and a swap file partition (300meg+) i made my swap 1gig which i found later to be a waste of time hehe.
The next step will give u a choice to install 2 boot loaders (lilo or grub). The boot loader gives you a choice at system startup of which OS u would like to load.
The rest is pretty much self explanatory. if u need any help just buzz
