Most first timers don't need to nuke their Windows installation, mess with re-sizing a hard drive, or hassle with dual booting. Most laptops and PCs are capable of running Fedora or any other OS in a virtual environment.
Get and install the windows version of VirtualBox, VmWare Workstation or VmWare Player. VMWare Workstation costs money. There's zero cost for either VmWare Player or VirtualBox. You should have at least 2 GB RAM installed on your machine (1 GB for Windows and 1 GB for the virtual machine). You should have at least 500 MB of disk space available for creation of a virtual disk drive.
