There appear to be two types of Ubuntu installations: 'live' installations (typically USB or CD) and what I'm going to call 'full' installations (typically on an internal HDD).
Full installations can use "Startup Disk Creator" to create live installations, and live installations ask if you would like to try Ubuntu or install to a hard drive, creating 'full' installations.
How can I create another 'full' installation on another partition/disk, without creating an intermediate bootable 'live' medium? This seems like it should be simple.
A computer with four partitions: swap, /home, / , and one blank. Ubuntu 12.04 Desktop is currently installed on partition 3. I would like to install 12.04-server on the 4th partition. I have the .iso saved on the drive (/home partition). How do I perform a full (not 'live') install of 12.04-server to the fourth partition without buying a USB stick or CD drive?
