I'm trying to create a custom iso of an Ubuntu install - that way, I can install a bunch of educational programs & plugins on one computer and they'll automatically be on every computer I install the iso on.
What I'm doing right now is using remastersys to create a distributable version of Ubuntu. It creates the iso, but I can't burn to a CD (the file is 1.1gb) and the computers in question don't have DVD drives. So I tried putting the iso onto a USB instead via the included Startup Disk Creator. It boots and installs fine for the most part, but at the very end of the installation, it tells me that it can't install Grub.
Does anyone have any idea how to fix this?
Or, alternately, is there a tool other than remastersys that you'd suggest using for creating a distributable iso?
