Your computer has no CD/DVD drive ?

A simple way to install most older and current linux systems is by creating a bootable USB stick.

Some distributions have a option to do this from the live CD, but you still have to first boot from that downloaded iso file.....

UNetbootin can also be used to load various system utilities, including:
