No Video After Install

Hi All, Trying to install OSMC on my old apple TV ive setup my USB Drive with the HDD installer, pluged it in and it boots, then tells me to unplug wait 10 seconds and plug in, i do this.

i can then hear what sounds like the install process (HDD Noise) and the light eventally turns off. waited like this for 10 mins then rebooted, i can hear what sounds like it booting but no video.

Any ideas whats going on ? BCM card installed Connected via HDMI

It means you may need to configure X11.conf to support your tv

Thanks, Seems to work Fine when installed on a USB Stick, ill Take a look at the X11 And Confim, Tv is pretty modern (HDMI 1.4) i shall have a play!
