You can either let UNetbootin 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.
Download for Linux.
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 loads distributions either by downloading a ISO (CD image) files for you, or by using an ISO file you've already downloaded.
The current version has built-in support for automatically downloading and loading the following distributions, though installing other distributions is also supported:
- Ubuntu (and official derivatives)
- 10.04 LTS
- 12.04 LTS
- Daily CD Images
- Linux Mint
- Arch Linux
- Damn Small Linux
- Puppy Linux
- Sabayon Linux
- SimplyMEPIS 8
- AntiX 8
- Frugalware Linux
- Parted Magic, a partition manager that can resize, repair, backup, and restore partitions.
- SystemRescueCD, a system repair, backup and recovery tool.
- Super Grub Disk, a boot utility that can restore and repair overwritten and misconfigured GRUB installs or directly boot various operating systems
- Dr.Web Antivirus, F-Secure Rescue CD, and Kaspersky Rescue Disk, which remove malware from Windows installs.
- Backtrack, a utility used for network analysis and penetration testing.
- Ophcrack, a utility which can recover Windows passwords.
- NTPasswd, a utility which can reset Windows passwords and edit the registry.
- Gujin, a graphical bootloader that can also be used to boot various operating systems and media.
- Smart Boot Manager (SBM), which can boot off CD-ROM and floppy drives on computers with a faulty BIOS.
- FreeDOS, which can run BIOS flash and other legacy DOS utilities.
Installation & Screenshots.
- 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.
- 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. Note that Live USB drives are bootable only on PCs (not on Macs). 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.
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.
Download and run UNetbootin, then select the "disk image" option and supply it with an ISO (CD image).
UNetbootin doesn't use distribution-specific rules for making your live USB drive, so most Linux ISO files should load correctly using this option. However, not all distributions support booting from USB, and some others require extra boot options or other modifications before they can boot from USB drives, so these ISO files will not work as-is. Also, ISO files for non-Linux operating systems have a different boot mechanism, so don't expect them to work either.
