UNetbootin is a simple no frills tool, the type of program that used to populate the shelves at Egghead and other software stores back before the Internet changed everything. Using it to make a bootable USB drive from an ISO image is so easy even your grandmother could do it. Not only that, the application comes equipped to download and copy quite a few tools that might come in handy on a rescue drive.
The first choice you make after opening UNetbootin is between ???Distribution??? and ???Diskimage.??? If you choose the first option, you then choose a distro and version from two drop down list boxes. If the distro you need is on the list, this saves you the chore of downloading the image yourself, it’s all done for you. In addition, this list includes the tools you need for a good rescue operation, such as Parted Magick, Dr. Web Antivirus and NTPasswd.
