It works like a charm but now we are thinking of going Virtual and prepping Virtual CentOS servers under VMware ESXi. However, to have the same "Boot and Install" functionality I see no other solution than Booting a VMware machine from an ISO. So, what I would like to do is to take the Bootable USB and make it into an ISO. Any ideas?

I have a bootable usb key that I want to turn into a bootable iso image - not how to boot it.

So, it's fairly straightforward as long as you change the emulation type to 1.44 Floppy (most bootable USB's do *not* emulate a floppy disc when booting; 'dd' won't do that for you by itself), and use 512 as divisor of the /boot folder's image file size in bytes when setting the Sectors To Load option.
