I am trying to install centos onto another one of my machines, and I am new to Ubuntu. When I downloaded centos the operating system came as two .iso images. So far I have been unable to figure out how to mount the two images onto a single 32gb flash drive to do a full install on the OS.

I also want to have Ubuntu on the same flash drive. So when I boot my computer, and boot to the flash drive I can select whether I want to install CentOS or boot Ubuntu.

I'm using Ubuntu 12.04 LTS. Here is a link to the CentOS file I'm using

You want to make a CentOS usb installation media or get several installation media in a single USB? –  Braiam Sep 23 '13 at 22:08
