Install Linux from USB, preparing USB drive to start a installation over net (Red Hat or Fedora)

More and more frequently, we can meet the need to install an OS (Red Hat or Fedora) on a physical server without DVD drive.

In these cases from the DVD ISO we can prepare a USB flash drive to perform a network installation.

The steps are:

  1. We mount the iso with:
    mount -o loop DVD.iso /mnt
  2. Assuming that the pendrive you have clicked on /dev/sdd, copy the image (eye that will erase everything you have):
    dd if=/mnt/images/efidisk.img of=/dev/sdd
  3. Umount the iso:
    umount /mnt

We have the pendrive ready to start.
