How to make bootable flash with fedora 23 in?

edit

We can put boot.iso ( aka netinstall and or bootable-rescue) and live images on a usb pen drive, let suppose that pen is mounted on /dev/sdb.

First must be on vfat or else format usb with:

You may want to run lsblk to find out what /devname was assigned to your flash drive.
Warning this clean all the data without asking, be sure the letter after /dev/sd is correct.

mkfs.vfat /dev/sdx1

after and always as root do :

dnf install livecd-tools
/usr/bin/livecd-iso-to-disk boot.iso /dev/sdb1

After you may test if pen boots correctly:

qemu-system-i386 -hda /dev/sdb -boot c

in this operation you may need give permissions to normal user with :

chmod o+rw /dev/sdb* (as root)

A brand new application called MultiWriter has just hit the Fedora 21 an so on:

gnome-multi-writer

You can also do it by running in a terminal (after downloading iso image from getfedora.org, and still supposing your pen drive is mounted on /dev/sdb):

sudo dd if=/home/<user>/Path-to-downloaded-iso/nameoffedoraimage.iso of=/dev/sdb

This will delete everything on your pen drive and create a bootable usb of fedora.

use unetbootin

su
dnf install unetbootin
