How to create bootable USB from an ISO image

One invaluable feature of modern computers is the ability to boot from removable storage such as USB flash drives and external hard drives.¬†Despite this feature’s availability, it isn’t easily utilised because there isn’t any native support available in Microsoft Windows (which as of 2012, is still the most common Operating System in the world).

We came across a great application called UNetbootin. It allows you to ‘burn’ an ISO image to a USB flash drive.

UNetbootin

Download here: http://unetbootin.sourceforge.net/)

To ‘burn’ an ISO image to the USB flash drive, follow these instructions:

  1. Install it as you would any other application.
  2. Load UNetbootin from your start menu.
  3. Select the Disk Image (second option down).
  4. Select ISO from the drop down.
  5. Click the three periods to browse for an ISO image.
  6. Make sure the Type is set to USB drive and the letter corresponds correctly.
  7. Click OK.
  8. The process will take a while, so grab a cup of tea!

You can also use UNetbootin to create Linux live boot disks.

    I did, but the pc doesn start with the USB ( ..of course I ‘ve changed the boot start on BIOS ) ..what s problem ??

  2. Norton says:

    It does NOT work. I’ve also tried tuxboot and I’m getting Operating system missing when booting!!!

    • Aidan says:

      If you’re getting ‘operating system missing’ when the image is loaded into the bootstrap then you havent extracted the files correctly. The boot image should be within the root dir otherwise it will not boot.

  3. Norton says:

    And the windows tool also doesn’t work !!! The program doesn’t even start… This is really potatic…

  4. Alex says:

    I have already problem, don’t boot.I try on 5 pcs but nothing to do.My usb disk crated with acronis boot ok.

    Mah, probably is a fake application (unpackage and copy only)

    • lol says:

      LOL, probably the most used app for making bootable usb devices should be a fake?
      Your inability to understand it doesn’t make it fake.

    You rock!!

  6. eric k says:

    you have to format the usb stick fat32, run the app, then boot.

    it hung up at init for me anyway.

  7. Tony says:

    You rock. Just used this for Falcon 4 boot on netbook. Worked like a champ.

  8. Adaio says:

    Some of the motherboards dont accept Booting from USB such as mine one, all I can Boot from is CD Drive.

    • Ben says:

      do a search for plop boot manager you boot this first. it will then give you the options of the things you can boot including USB. this is what i do. you can write it to floppy, cd straight to the hard drive and lots of different options. just make sure you read the site cos depending on how you want to use it depends on how you set it up.

    UNetbootin worked perfectly for me on Ubuntu 10.10.
    I now have a bootable USB stick made with an iso of Hiren’s Boot CD (didn’t feel like burning it).
    UNetbootin probably doesn’t work for non-Linux operating systems, as is written on their site.

  11. Dylan1170 says:

  12. Neo says:

  13. EIF2012 says:

    Maybe a stupid question but if you wan’t to create a startup USB stick for Linux do you also need to use a linux os and the linux application to create the startup USB?

  14. rj39ga_al at yahoo says:

    i followed the steps, used Windows XP iso file, all seemed to do fine but when I put the flash drive and try to boot from it, it comes up with UNetbootin blue box that has Default in it thats it, keeps timing down from 10 seconds and just start timing down again… over & over,,, when I hit the tab, command line comes up /ubnkern initrd=/ubninit
    any suggestions ?

  15. Ginny says:

    Same problem as rj39ga_al at yahoo. Blue screen with 10 second countdown then back to 10. Same results with Esc.

  16. Parker says:

    Same with me but I am using a windows 8 iso file. Dont think this software works for non linux based systems :l

  17. Noble K Varghese says:

    Try live usb creator. it’s free

  18. anna says:

    this is really useless and stupid software, wasted 30 minutes in my life. I suggest you stop programming in software since you have a very limited skill and not able to make anything good for us, may be go back to the school before writing any software. Totally useless and stupid.
