I've an iso file for RHEL in one of my pendrives. Now I want to first make the device bootable, so that later on I can put RHEL as a VM. Now the problem is even after following the instructions to install at http://www.pendrivelinux.com/using-unetbootin-to-create-a-linux-usb-from-linux/ , I still couldn't install it, and thus couldn't make it bootable.
I am still not getting the real issue. Or is there any other way of installing any such package which could make the USBs as boot-able?
EDIT : My purpose here is to install RHEL via KVM. I have Ubuntu 14.04 as of now, and I have the iso file for RHEL in a pen-drive downloaded from a different system.
