Re: [Trisquel-users] How can a Trisquel live DVD be added to a data DVD ?

[xsupersheepx]

Use isomaster to add a folder to the ISO and fill it up with your extra  
files, then save it as a new iso and burn it. Your DVD should still boot  
Trisquel just fine.

Run the following commands:
sudo apt-get install isomaster
isomaster
Good luck.
