Whenever your Windows machine gets some booting problems and hangs before completely loading the OS, does it mean you are trapped? Not necessarily. How are you going to take out all those important files stored in your hard drive? One way is with the help of Ubuntu Live USB Imager, from phatWares.com. This very straightforward tool can help you place a full Ubuntu operating system on your preferred USB drive.
There are two ways you can put a live image into your USB device - either you use an existing Ubuntu .ISO image from your hard drive, or go directly to your Ubuntu install CD. There is a third option though – you may download the ISO image from the respective sites of Ubuntu, SuperOS (formerly Super Ubuntu), Kubuntu, and Xubuntu.
The main advantage of this tool lies in the fact that you can create this portable Ubuntu directly from your Windows machine - there is no need to have Ubuntu installed. For extra security, it allows you to create persistence files ranging from 256 MB to 4096 MB, which will also help you to maximize the your pen drive’s space.
It has been tested and certified by avast! 4.8 & Kaspersky IS 7 for virus, spyware, and worms.
