[server] ubuntu server 16.04

hello

I have had a ubuntu server 14.04 runing in a machine without any issues.

Yesterday I decided that was time for upgrade and fresh install ubuntu server 16.04

I am runing a machine with 2 hard drives...I installed via usb dont have a cd/dvd media.

First thing I notice is no login prompt after boot, only appears after CTRL+ALT+F1 after that i login etc

The problem is when I remove the graphic card because I dont want it there no need for that, and the system doesnt boot and I cant ssh nothing.

thanks in advance for the help
