Hi folks! I am trying to install Debian on my new HP z240 box. I tried Debian 8 and Debian 9 RC2 installers, but neither succeeded. When I choose to boot from a pen drive I see "Debian UEFI Installer menu". Then I choose "Install" and get a black screen. Switching to a virtual console with Ctrl+Alt+F1 doesn't work.
To eliminate possible problems with hardware I tried to install the latest stable Ubuntu 16.10. Installation went without any problems. Where should I look and what can be wrong here? Thank you, Kostia
