Compressing with Gzip and Zip
Compressed files use less disk space and download faster than large, uncompressed files. You can compress Linux files with the open-source compression tool Gzip or with Zip, which is recognized by most operating systems.

UNetbootin (Universal Netboot Installer) is a cross-platform utility that can create live USB systems and can load a variety of system utilities or install various Linux distributions and other operating systems without a CD.
This installation mode creates bootable USB flash drives and bootable USB Hard Disk Drives; it is a Live USB creator.
- Cross-platform (available for Windows, Linux and Mac OS X)
- Non-destructive install (does not format the device) using Syslinux.
- Supports mainstream Linux distributions, such as Ubuntu, Fedora, openSUSE, CentOS, Debian, Gentoo, Linux Mint, Arch Linux, Mandriva, MEPIS, Slackware as well as FreeDOS, FreeBSD and NetBSD.
- Can load a variety of system utilities, such as Ophcrack, BackTrack.
- Other operating systems can be loaded via pre-downloaded ISO image or floppy/hard drive disk image files.
- Automatically detects all removable devices.
- Supports LiveUSB persistence (preserving files across reboots; this feature is for Ubuntu only)
Multiple installs on the same device are not supported.
It is worth noting that UNetbootin’s meta-data is very out of date. For example, the latest version of Linux Mint offered in the drop-down menu is version 10, whilst the latest official release is version 14 (at time of writing, February 2013). However, UNetbootin can still be used to write a bootable Mint 14 ISO file onto a USB device, if the user first downloads the ISO file manually.
How to install UNetbootin in Ubuntu :
Using these few commands, downloading and running it will work.
