· You will need one of the Fedora 15 Live CD ISO images that corresponds to your hardware architecture (i386 or amd64), and which can be downloaded from fedora home page.
· You will need a 700 MB CD, because when the download will finish, you need to burn the ISO image with your favorite CD/DVD burning application (Brasero on Linux, or Nero, CDBurnerXP, Roxio on Windows).
· You must have a minimum of 10 GB free space on your hard drive, for the Fedora 15 installation.
Great, now let's begin. Insert or leave the CD in your CD/DVD-ROM device, and reboot the computer in order to boot from it. Hit the F8 or F12 key (depending on your BIOS) to select the CD/DVD-ROM as the boot device. Boot from the CD.
Fedora 15 will automatically boot in 10 seconds.
Wait for the system to load.......
