Have you got a usb stick? You could mount the installer .iso in a temp directory, copy the boot image off, then make the usb bootable with the boot image contents. Then boot off the usb, type linux askmethod at the installer prompt, then select hard drive as the location of the iso. Enter the partition you have the iso on, then the installer should begin.
So steps would be:
1. Mount the installer .iso to temp dir:
mount -ro loop /pathto/fedora-i686-Live.iso /mnt/tmp
2. Create a bootable usb stick:
#Assuming your usb stick is /dev/sdc
dd if=/mnt/tmp/images/diskboot.img of=/dev/sdc
3. Boot from usb, then type at the boot prompt:
4. Select Hard drive from the installer locations.
