So, I’m still trying to figure out the Fedora boot, but in the meantime, I tried to figure out how to boot from a few recovery systems. First off, let’s try Parted Magic. This one is pretty simple since they provide a “USB” version. If you extract that, you’ll find a boot and a pmagic folder. Copy the pmagic folder to the USB drive. In boot/grub/grub.lst, you’ll find a whole bunch of boot options.
