You can install Fedora 11 from its ISO file(s) on your hard drive. You need at least four files...
Note 1: You can also use the CD ISO files instead of the DVD ISO file. Only the first two CD ISO files are needed for the default installation.
Note 2: You can extract vmlinuz, initrd.img, and install.img from the ISO file or download them from the Internet.
Somehow get those files on your hard drive in a compatible partition (FAT32, ext2, ext3, not NTFS, not LVM PV). I recommend that you create a small FAT32 partition for these files. About 5 GB is enough. Copy the ISO file(s), vmlinuz, and initrd.img to the root directory of the partition. Create a subdirectory named "images" and copy install.img there. After the installation you can leave this partition for future re-installs.
You need GRUB to boot the kernel (vmlinuz) and the initial ramdisk (initrd.img). Windows cannot boot them directly. If your Windows system is XP or W2K, then GRUB4DOS is a simple way to boot the Fedora installer's kernel. If your Windows is Vista, then you can probably use EasyBCD and its NeoGRUB to do the job.
