Welcome!
You really have two options:
1) Create your own boot disc
2) Purchase a boot disc
If you are on a modem or slow DSL connection, #1 is not really a feasible option. If you have a fast connection, then download the version of Fedora you want from
www.fedoraproject.org.
You will need to make sure you get the right platform (you probably have a 32-bit computer and should use this link for Fedora 8:
http://download.fedoraproject.org/pu...8-i386-DVD.iso ).
It will take some time to download. Be sure to save this to your computer when done. You then need to burn a DVD from the iso image. This depends upon what softare/OS you have. You should check online for instructions or provide info about what program you are using so myself or someone else can walk you through that. You need to be careful how to set your options when you burn so that you get a bootable DVD and not just the iso file copied onto disc.
If you can't download it or you'd rather not spend several hours downloading, then you can purchase a disc. There are vendors listed on the Fedora website. I don't have any recommendations for which one.
Another option is to check out your local bookstore (or library - if you bring a laptop you can copy without checking out the book). Most thick Fedora books include an install DVD. The "Linux for Dummies" book also includes a Fedora DVD, to my knowledge. You may get an older version, but you can always update once you have it installed.
One final option is to copy a friend's DVD, if you know someone with it. It's not likely, but it doesn't hurt to ask. You could even try calling a local college or university's computer science department to see if someone has one.
