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. Thomas

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. -------------- next part -------------- A non-text attachment was scrubbed...

Did this change in a recent release?
