I've been poking at this for quite a while, and have never been able to get it to work. I've found a couple links with some partial truths: http://syslint.com/syslint/how-to-make-a-usb-boot-disk-for-centosrhel-from-i... http://brakkee.org/site/2013/05/09/creating-a-usb-install-for-centos-6-4/
The first one talks about converting a standard iso to a 'hybrid' image, using: 'isohybrid'. But it then instructs the reader to make a vfat partition on the thumbdrive, and DD the image to that partition. This seemed odd to me, since the image itself should have all that info. I've used hybrid images before, such as Linux Mint, and was simply able to dd directly to the device itself, ie: dd if=/path/to/hybrid.iso of=/dev/sdb (where sdb is the thumbdrive). But, I went along with it, and it failed-- unable to find 'isolinux.bin'. I've read this error is due to old/incompatible firmware, but I've booted other thumbdrive hybrid-built images many times, and have never seen this except in CentOS installations. So, I tried doing a dd directly to the thumbdrive device, rather than the partition.
This actually looked like it was going to work. I got to the initial installer page, and proceeded through the Language and Keyboard questions. It then forgot where itself was, and asked me where the media for installation was. I selected Hard Drive, and /dev/sda1 showed up as default. I hit enter, and it continued further. But then it again forgot where the media was, and couldn't find the installation media.
The second URL/instruction wouldn't boot at all.
Has anyone successfully installed via USB? I remember reading some multi part instructions where the USB drive is formatted with some special tools, often involving Windows, and various files need to be copied to the USB drive. But I was hoping we were passed that by now. But then again, Dell firmware updates still want me to make a DOS bootable floppy. So, I'm usually not surprised when I hear something like this. :)
Thanks!

I did an install from USB disk a while back. It mostly worked. The only thing I had issues with is that the USB disk occupied a slot and I had to tell grub which partition to boot from.

Just checked it out. Looks like a lot of frustrated people, with no real resolution. I'll find a USB DVD drive and use that, until a hybrid ISO becomes available.
Thanks!

this has worked for me, using a Windows machine to prep the USB stick http://www.centos.org/forums/viewtopic.php?t=29829
and this tool was even easier to use, you can setup the USB stick on either a windows or linux box. http://unetbootin.sourceforge.net/
I nearly always use the CentOS 6 MINIMAL install, its hardly bigger than the NETINSTALL, and less hassle to setup. once its up and running, I yum install anything else I need. I prefer minimal installs to very comprehensive ones, yum updates are much faster when you aren't updating tons of packages you'll never use.

I used the main "Older Method" described on the Wiki last month with a 6.4 ISO and it worked flawlessly:
http://wiki.centos.org/HowTos/InstallFromUSBkey
having first tried the livecd-iso-to-disk method which I was unable to get to boot on my new laptop (although it would boot other laptops).
So my advice is to try a few of the different methods out there if the first one you try doesn't work for you.

I assumed too quickly that the OP wanted to create the USB key using Windows. If he wants to create it using Linux, it's easy to do so using the instructions in the Wiki.
