ISO Boot HyperV Generation 2

[OGUER]

Hi,

we can't boot ISO on a Generation 2 VM (HyperV - mount with SCSI)
(secure boot is off)
it's working with Generation 1 (mount with IDE)
the default debian 8.6 ISO work perfectly.

What's wrong ?

I was under the impression that the 3CX ISO was not EFI boot compliant or capable and that is why it does not work under HyperV Generation 2.
