3CX Debian Install from ISO on Windows Hyper V- Blank Screen

[SimonCC]

I am trying to install the 3CX Debian ISO (latest version) on a Windows Hyper V virtual machine using the virtual machine manager.

The vm starts ok and I select install. I see the early screen to enter host name and domain name, but then after this point, I just see a blank screen. If I press Control C, it then moves onto the next screen to Select a Language which works ok until Configure the Keyboard, then goes blank again after this point.

I have successfully installed Debian server without 3CX on another virtual machine, and did not see any of this.

Please help?

Are you using a gen2 VM?

What happens if you create a new VM and VHDX?

Try downloading the ISO again?

It;s Gen1 VM
I downloaded latest ISO and saw same issue.
But it was using dhcp on network, and I have a firewall blocking outbound
I have now set a static ip address and allowed outbound access, and I am now getting further

So issue with me it seems! thanks for your help.

Please do not block anything during the installation, the Debian installer will need to access the internet during setup and then the 3CX installer will also need to access the repositories.

If your firewall is outbound restrictive then the installation will ultimately fail.
