Booting from the USB requires that there is a syslinux directory to boot off of. In EL6, there is only isolinux, which is what booting from a DVD uses. You should be able to copy isolinux to syslinux, rename the files from s/iso/sys/ and then update syslinux.cfg to point to the USB drive to boot from. Here's an example from my setup:
Perhaps something went wrong with the 6.7 DVD, I haven't tested yet. It is definitely supposed to work by just using dd to a USB stick. Both 6.5 and 6.6 DVDs works just fine and so does the 6.7-network- install iso. I just installed a node 10 minutes ago using that one booted from a USB stick.
I just dd'ed the 6.7 DVD1 image to a usb key and booted fine with it on a machine with normal BIOS.
I'll test it on a UEFI machine later, but it seems to work fine.
One thing to make sure is that the key is unmounted before you start // I used this command:
sudo dd if=./CentOS-6.7-x86_64-bin-DVD1.iso of=/dev/sdc bs=4M
(Also make sure to copy to the device and not a partition .. ie, not /dev/sdc1 .. /dev/sdc)
And make sure to use the command:
sync
after the dd .. and umount/eject the device if it remoted before removing the key from the machine where you are copying it.
My apologies for the mis-information.
Did this change in a recent release? (The addition of syslinux to the ISO, that is)
