Ok Dell finnally stopped shipping XPS's with legacy support. Now I'll need to use the UEFI methods only.
So I'll have to learn the new ways of booting clonezilla using something other than pxelinux.
I see some posts about it but no notable configuration files.
I would like to see some configurations on booting over PXE using a UEFI boot loader.
I'll do some more research but documents on such seem few and far between.
I think I might just be able to use grub but not sure how to give it network options to get files like I do with pxelinux.
I had pxelinux working so nice and then Dell throws this at me.
Anyways I figured out the part to switch on UEFI and legacy on the dhcp server side.
I used the following on server 2012 -boot-both-legacy-bios-and-uefi-96ecf95a504
