Usually, if I want to make a bootable CD for linux (Ubuntu. Mint, Debian, whatever) I just burn the ISO to CD and then restart the machine that I intend to install linux on with that CD inside it.
But to create a "bootable" USB drive, I need to install this software (or its likes) called UNetbootin and use it to map the ISO to the USB drive.
My question is: why?
What is so special about CD technology that it allows me to just burn the ISO to it and install linux from it, whereas with a USB drive I need to go through this intermediary step? Thanks in advance!
