This it is a very easy process to create an installable usb key:

1.  Download the iso file from a mirror.

2.  Check the sha256sum with this from the command line:

sha256sum <isoname>

3. verify the output is the same as this list (for CentOS-6.7):

http://mirror.centos.org/centos-6/6.7/isos/x86_64/sha256sum.txt.asc

4.  Find the name of your USB stick, from the command line (as root) you
can do:

fdisk -l | grep Disk | grep dev | grep -v mapper

You can also use the GUI disk tool

5.  Use this dd command to copy to a usb stick:

dd if=<path_to_iso_file> of=/dev/<drive> bs=4M

so if the usb device for the key is /dev/sdc , and you are at the CLI
and in the directory where the iso file is at (as the root user), then
the command to copy the NetInstall iso file to usb is:

dd if=./CentOS-6.7-x86_64-netinstall.iso of=/dev/sdc bs=4M


Netbootin may or may not work (I have had problems trying to use it),
but just dd'ing the iso file to a usb stick will.
