The Linux distribution can be downloaded directly from its Sourceforge page. It comes as a 438 Megabyte self extracting executable that requires 1.86 Gigabytes on the computer’s hard drive after extraction. Users can then immediately start Ubuntu in Windows by clicking on the run_portable_ubuntu.bat file that is located in the root directory of the software program. Starting portable Ubuntu in Windows will open a command line window which will remain open all the time. This command line window contains information about background processes and the state of the Ubuntu system.

The Ubuntu dock at the top center of the screen will be opened and displayed giving users access to Applications, Places, System and applications like Firefox. Talking about applications. The usual add / remove applications menu can be accessed in portable Ubuntu to install additional applications on the computer system.

One could think that running an operating system inside another operating system would surely demand lots of system resources. This is surprisingly not the case. Running Ubuntu portable requires less than 50 Megabytes of computer memory that are occupied by its processes.

Main question however is why someone would use Ubuntu portable instead of the other options outlined above. One of the main reasons is that it is the least complicated to use. It cannot get easier than extracting and running the Linux distribution. Even Live CDs might require changing the boot sequence from hard drive to CD in order to run the distribution that way.

The portable application gives access to many Ubuntu applications and features which can be a great way of taking a look at the options the distribution offers.

It comes close to the Linux user experience but does not provide it fully. There is still the Windows Taskbar, icons and wallpapers that make the system look much more like a Windows system than a Linux system. Interested users can download it right at the developer’s website at Sourceforge.
