How To: Install Portable Linux Ubuntu on a bootable USB Flash Drive from SUN VirtualBox. Recently I have got a shiny and beautiful Chrome finished, shiny Transcend 8GB USB flash drive.
What did I first think to do with it? Put Ubuntu on it, of course ;) There are many ways to create a live USB drive carrying an operating system like Ubuntu, but the method I will describe further is mainly based on using SUN's VirtualBox. For those who don't know what VirtualBox is visit this Wikipedia link.
While the method described on the Ubuntu documentations implies installing a Live CD image on a USB flash drive, which would then need to extract and load the operating system in the RAM, the method that I will describe on this page implies installing a fresh operating system on a bootable flash drive that will work the same way as from a real HDD (except the speed, of course). Thus, you should have a good bootable USB 2.0, with decent I/O data processing speeds, with at least 4GB (considering that the operating system itself weighs ~2GB, Karmic Koala).
