Generally: You can forget to try to install BlueOnyx from an USB stick
based on our ISO. If you take our ISO and convert it to an USB stick,
it'll not perform the BlueOnyx install with the *required* custom
kickstart script. Instead it'll run off and will install *something*,
but not really a functioning BlueOnyx.

The reason for this is: The ISO's boot menu passes (depending on
selected option) the kickstart as a parameter to the startup procedure.
Usually this gets lost or is rendered non-functional when you convert
the ISO to USB.

As for a true EFI-build: The *only* way for me to build an EFI capable
ISO is to build the whole thing on my office workstation (which has EFI
enabled) inside a VirtualBox VM with enabled EFI. Means I need to
download around 1800 RPMs, let the build box mix it up (45-60 minutes)
and then I got an ISO. After testing both EFI and non-EFI modes by
installing the ISO into another VM I need to upload the ISO to the
mirrors, which takes me hours from my shitty office internet (the
downlink is fast, uplink is crap).

I'd rather build the ISO's in the datacenter on dedicated build boxes,
where my scripted environment does the building and testing in an
automated fashion. But that means (for the time being): No EFI, as the
servers either don't have EFI or have it disabled.

Now if installing off the ISO or from a DVD isn't possible and you can't
do w/o EFI? Install a regular CentOS 7 and then do a manual 5209R
install based on this instructions:
