I've downloaded the daily Ubuntu 12.04 iso.

I currently have windows 7 x64 operating system installed.

How can I make a bootable usb from the Ubuntu iso?

With UNetBootIN, for example. I like Pendrive Linux Easy USB Creator very much, but it doesn't support béta's without some tips 'n tricks. Testing an alpha isn't as simple as you think by the way, some experience is useful ;)

Download for Windows

Unetbootin is available for Windows, Mac, Linux (Lots of distros)

I've been testing ubuntu alpha's since 8.04. However I used CD's till now. There's a way of doing it through Virtualbox. I want to find a clean way. I tried Pendive Linux method. It didn't work. I'll try UNetBootIN. Thanks! – Akshar Patel Dec 12 '11 at 15:38
Virtualbox will boot the iso directly, no need to burn a CD or put it on a flash drive. unetbootin is a nice option, for additional options see – bodhi.zazen Dec 12 '11 at 16:04

This is a nice way for normal iso's. However, the iso I'm trying is in alpha state. This method does not work for it. – Akshar Patel Dec 12 '11 at 17:12

Open Unetbootin daily_live ...that surely will boot.

Ubuntu ISOs (since 11.10) are hybrid, they are both CD and USB bootable. On Linux, you can just cat them to a flash drive.

On windows, follow the instructions here:

Windows 7

Right-click on an ISO image and choose 'Open with > Windows Disc Image Burner'.

enter image description here

Select a disk burner (drive) and choose 'Burn'. If you check 'Verify disc after burning', it will confirm that the ISO image has been burned correctly.

enter image description here

Windows Vista / XP / Server

Download and install the appropriate version of ISO Recorder. Insert an unformatted DVD into your burner. (Note: You can only burn DVDs with this tool from Vista.)

enter image description here

Open Windows Explorer, find your ISO file, right-click and choose 'Next'.

Try Rufus. It's free and works better than unetbootin or live usb creator. It succeeded where both have failed for me.

In order to make an Ubuntu live USB for installing Ubuntu, use UNetbootin (Windows<=Windows 7/Linux/Ubuntu Software Center). The flash drive you use should be 1GB or larger (2GB or larger for Ubuntu 14.04 and onward), plus whatever additional space on the USB drive you want to use for persistent file storage, and formatted to FAT32. UNetbootin will automatically format the USB flash drive to FAT32 if it is not already formatted to FAT32. In either case the formatting procedure will delete all of the files that are already on the flash drive.

It is very important to verify that the device that you are installing the Ubuntu live USB to is indeed your flash drive, so that you don't overwrite any of your system or personal files which may make your operating system unbootable. In Ubuntu you can find the device name of the flash drive using Disk Utility (or Disks if you are using Ubuntu 13.04, 13.10 or 14.04 and onward). In the picture below the name of the flash drive is /dev/sdc1 where /dev/sdc is the device name of the flash drive and the 1 after sdc means UNetbootin will install the Ubuntu live USB on the first partition on that device.

enter image description here

The Ubuntu live USB flash drive that you make this way will be bootable from a PC. In order to enable your computer to boot from the USB flash drive, you must enter your BIOS menu by pressing one of these keys: Delete, F2 or F10 as soon as the motherboard splash screen appears when the computer is booting. In the BIOS menu, you need to change the boot order so that the USB flash drive, which is usually called USB-HDD in newer computers, is the first entry in the boot sequence, and then save your new BIOS settings and exit the BIOS setup.

Got 'em, you've got to change the name of 12.04-alpha.iso (or something like that) into ubuntu-11.10.iso, and you're fine :)

Tried that method.. didn't work! – Akshar Patel Dec 15 '11 at 21:08

I haven't seen it mentioned, but Linux Live USB Creator is far and away the best I've tried. It's quick, easy, and allows Persistent Mode with no hassle. It is Windows-only, however.

In case you are using newer computer there is a good chance it support UEFI.

Now I understand this is an old post, but if someone have the same problem nowadays many of this answers just won't work. So if you want to create a bootable USB from Windows with all the new technologies supported (UEFI, GPT) you should use Rufus.
