Just revisited this - I set up a brand new ubuntu desktop and installed nothing but Fog on it - I reformatted the problem laptop and did nothing but put 1 txt document on desktop. I also reset the toshiba bios.
To check fog was working, I took a working laptop and did a quick host, an upload, and a deploy all successfully.
I then took the problem laptop, managed to get the PXE to boot to fog menu, did a ‘quick host’ first time, completed an upload (to a new image file) first time also, went to deploy it - and it got stuck at the same place as the video. Just dispays a ‘#’ when it should go to the blue screen.
I’m about to throw it all out the window.
