Whereas with other Linux distros like the Debian / openSUSE / Ubuntu it is possible to dd the ISO images on to a pen drive, boot from it and complete the installation [1]. The OP is trying to use a tool which supposedly makes a bootable/installable USB device. Search keywords "centos create usb boot disk" throws up helpful links. The manual methods may the way to go to achieve the objective. [a] <http://wiki.centos.org/HowTos/InstallFromUSBkey> [b] <http://shivasbase.blogspot.in/2012/03/create-bootable-usb-with-centos.html> [c] <http://thenubbyadmin.com/2012/05/04/how-to-make-a-bootable-centos-6-usb-drive/> All of the above essentially say the same thing. @OP please try the method outlined in above links and report your success/failure. [1] This is my preferred method, it eliminates need for an optical media and burning the ISO image to a DVD. FWIW, I have dd'd the CentOS ISO image to a pen drive. In the installer, choose one of the 'network' methods (http / ftp / nfs / cifs etc). Also make sure the CentOS DVD content is available over the network via the chosen method (my choice http). -- Arun Khan Sent from my non-iphone/non-android device
