I just used
File|Burn Disk Image on an ubuntu installation ISO. It completed yet it at least seems to not be bootable. When I place it in the boot USB drive and restart the linux laptop it reads the USB drive then punts on it and just shows Grub boot options screen (as loaded from the hard disk). When I then start ubuntu and open the DVD that way it shows the .iso as a file.
So two questions:
- is there a way to check a DVD to see whether it were bootable
- If as I suspect this process did not create a bootable DVD then what should I do differently on the burning process (from Mac) to obtain that result?
