Used Ctrl+Alt+Del to reboot and selected Upstart option which successfully booted the system but showing a message like "Upstart; Error while reading from descriptor, broken pipe." On my next attempt to boot using default systemd option I observed a message like "Systemd(1) Failed to setup API Bus. Connection timed out." , and then saw a window saying like "running low graphic" and then went into the same loop. Now, I can boot using Upstart option only not the systemd option. I'm using Dell Optiplex 755 with NVIDIA 8400GS Graphic card, Ubuntu 15.10 is installed on a external HD connected with one of external usb port.
