What are the differences between the following two scenarios?
- copying the content of a Linux ISO file to a USB drive (with the
ddcommand), then booting from it
- burning the ISO to CD, then installing from that CD
I've installed Ubuntu 12.04 from my USB drive by just using
dd command ( https://wiki.archlinux.org/index.php/USB_Installation_Media ) .
Many answer about Unetbootin but I didn't ask "how to create bootable USB". It seems in my scenario, what Unetbootin can do is needless.
- Is burning the ISO to CD just "copy" data from ISO to CD?
ddis just copy data from ISO to USB drive?
- if yes, why you need Unetbootin for usb bootable creating?
