I’m trying to do a test deploy of SNG7-PBX-64bit-2104-1.iso in an EFI VM to compare it to SwitchVOX.
VMWare 7, create new virtual machine, 2 vCPU, 4 gig memory, 100 gig disk, VM type: EFI
With EFI enabled, the default ISO boot option is automatically chosen after about 5 seconds, and blows away the previous state of the virtual disk without any prompting or warnings whatsoever.
Trying an install with BIOS boot mode, there is no nearly instant auto-selection and it sits at the boot menu waiting for me. Only EFI boot does that.
So apparently, attempting an in-place upgrade via the ISO with EFI enabled, can very easily be deadly to your existing disk state, if you are too slow powering on the VM, and then activating the console window.
Also, I am amazed all the boot menu default install choices are apparently designed to auto-wipe the VM disk with no prompting, unless you choose to do a custom install.

So anyway, with EFI enabled, on reboot after the auto-selected automatic default installation, all I see is a grub> bootloader prompt. So the EFI bootloader is broken using the default ISO boot choice.
… well tested software I see.
