In order to create a bootable CentOS installation USB thumb drive, there are several steps one must follow. The process often involves using a Windows box, which can be kinda annoying.
The Linux Mint distro has what they call a "Hybrid" iso image. (see: http://community.linuxmint.com/tutorial/view/744 )
This image can be written to a thumb drive and used for installation simply by performing:
# dd /path/to/image.iso of=/dev/sdb (where /dev/sdb is the thumb drive device).
This thumb drive can now be booted and used for installation. The same image.iso file can be written to CD/DVD to create the installation media as well.
Is this a complicated ISO build process? I'm frequently installing to systems without CD/DVD drives, so this would come in handy.
Thanks!

Centos ISOs have been "hybrid" for a while now AFAIK. Have you tried them and did not work?

=====================================
Nux: I just tried again, using an 8G thumb drive, with the CentOS-6.4-x86_64-minimal.iso image on my 64bit Dell laptop, and got a quick error: "no boot sector found on USB device" It then proceeded to boot the next device in the boot order list. I also tried it on 2 other Dell servers, and neither would boot the thumb drive.
I then dd'd the latest Linux Mint iso to the same thumb drive, and it worked fine on my laptop. So, perhaps the CentOS images can not (yet) be used this way. Have you tried?
Thanks for the reply!

i definitely had the same experience back then. Anybody had luck with simply dd a current CentOS iso. I wonder if RedHat supports ISOHybrid?

I have yet to EVER get that to work. The closest I get is have it start the boot/install process, then ask where the media/itself is. It forgets, and can't find the install media-- even though IT IS the install media. I've never figured that out. But, it is what it is. It does work nicely with the debian distros, such as Linux Mint though.

i broke down and stopped attempting this by hand and now use "multisystem" on my Ubuntu box.

Nope. I succeeded once by manually installing grub after an install. I have an external DVD R/W that a basically only use for installing CentOS.
