UNETBOOTIN | Install Linux from your Pen Drive

Make you Pen Drive Bootable Linux

Introduction

UNetbootin allows you to create bootable Live USB drives for a variety of Linux distributions from Windows or Linux, without requiring you to burn a CD. You can either let it download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you've already downloaded one or your preferred distribution isn't on the list.

How does UNetbootin work, and what does it do?

For the Live USB creation mode, UNetbootin downloads and extracts an ISO file to your USB drive, generates an appropriate syslinux config file, and makes your USB drive bootable using syslinux.

For the Hard Disk / "frugal install" mode, UNetbootin uses a Windows or Linux-based installer to install a small modification to the bootloader (bootmgr and bcdedit on Vista, grldr and boot.ini for NT-based systems, grub.exe and config.sys for Win9x, or GRUB on Linux, uses the bootloader to boot the desired distribution's installer or to load the system utility, no CD required. After the distribution has been installed, or once done using the system utility, the modification to the bootloader is then undone.

Does it have any spyware, viruses, trojans, or other malware?

No; though some anti-virus products (Kaspersky) raise "Trojan.generic" warnings due to the auto-uninstall feature, these are false positives. Just make sure you obtain UNetbootin from the official downloads page on Sourceforge not some shady third-party source. If you're absolutely paranoid, you can check the source code and compile it yourself.

Requirements

  • Microsoft Windows 2000/XP/Vista, or Linux. If you are having trouble with the Linux version, try the Windows version, it usually works better.
  • A broadband internet connection to download the distribution's .iso file (unless you're using pre-downloaded files)

Features

UNetbootin can create a bootable Live USB drive, or it can make a "frugal install" on your local hard disk if you don't have a USB drive. It can load distributions by automatically downloading their ISO (CD image) files, or by using existing ISO files, floppy/hard disk images, or kernel/initrd files, for installing other distributions. windowsDownload (for Windows) linuxDownload (for Linux) INSTRUCTION for WINDOWS screenshot screenshot INSTRUCTION for LINUX If using Linux, make the file executable (using either the command chmod +x ./unetbootin-linux, or going to Properties->Permissions and checking "Execute"), then start the application, you will be prompted for your password to grant the application administrative rights, then the main dialog will appear, where you select a distribution and install target (USB Drive or Hard Disk), then reboot when prompted. screenshot
  1. After rebooting, if you created a Live USB drive by selecting "USB Drive" as your install target, press the appropriate button (usually F1, F2, F12, ESC, or backspace) while your computer is starting up to get to your BIOS boot menu and select USB drive as the startup target; otherwise if there's no boot selection option, go to the BIOS setup menu and change the startup order to boot USB by default. Otherwise, if you did a "frugal install" by selecting "Hard Disk" as your install target, select the UNetbootin entry from the Windows Boot Menu as the system boots up.

Removal Instructions (Applicable only to Hard Disk / "frugal installs")

If using Windows, UNetbootin should prompt you to remove it the next time you boot into Windows. Alternatively, you can remove it via Add/Remove Programs in the Control Panel.

If using Linux, re-run the UNetbootin executable (with root priveledges), and press OK when prompted to uninstall.

Removal is only required if you used the "Hard Drive" installation mode; to remove the bootloader from a USB drive, back up its contents and reformat it.

Uninstalling UNetbootin simply removes the UNetbootin entry from your boot menu; if you installed an operating system to a partition using UNetbootin, removing UNetbootin will not remove the OS.

To manually remove a Linux installation, you will have to restore the Windows bootloader using "fixmbr" from a recovery CD, and use Parted Magic to delete the Linux partition and expand the Windows partition.

Installing Other Distributions Using UNetbootin

Download and run UNetbootin, then supply it with the appropriate ISO (CD image) file, floppy/hard disk image, or kernel and initrd files when prompted (see screenshot). Check your distribution's download page to find the appropriate file; if in doubt use the ISO file.

If you're loading an ISO file or floppy/hard disk image, that's all that's required (just press "OK" to start installing); otherwise if you're manually specifying kernel and initrd files and you'd like to specify special booting options, check the distribution's boot configuration files (usually after the "kernel" line in either isolinux.cfg, syslinux.cfg, menu.lst, or grub.conf) and supply them on the "Option" line.
