So if you don't want to dual boot, you are planning to wipe the installed OS and install Fedora only?

Do net books have a cd/dvd or a usb port?
I would assume they do.

Get Fedora or any of the many Linux distro burned to flash drive or Live cd/dvd.

I've found some computers act better with some versions so you may have to try a few to find a good fit
