I have downloaded Ubuntu 14.04.1 Server as a iso file and would like to know how i install it via a usb. The Macine im installing it on dosnt have a desk drive.
USB drive must be 1Gb size for the server (2 GB for the desktop). The procedure is simple:
1. Download live ISO image;
2. Copy it into USB drive (either ISO content or image itself; I've used some Live Usb Creator, see link in the page below);
3. Boot from USB drive. Details: https://help.ubuntu.com/community/Installation/FromUSBStick
