This section discusses how to install Fedora on your system without making any additional physical media. Instead, you can use your existing GRUB boot loader to start the installation program.
12.1. Retrieving Boot Files
To perform an installation without media or a PXE server, your system must have two files stored locally, a kernel and an initial RAM disk.
Copy the vmlinuz and initrd.img files from a Fedora DVD (or DVD image) to the /boot/ directory, renaming them to vmlinuz-install and initrd.img-install. You must have root privileges to write files into the /boot/ directory.
