Ubuntu can be installed from a USB flash drive. This may be necessary for netbooks and other computers without CD drives and is handy for others because a USB flash drive is so convenient.
 Booting from a USB flash drive created with this utility will behave just as if you had booted from the install CD. It will show the language selection and then the install menu, from which you can install Ubuntu onto the computer's hard drive or launch the LiveCD environment.
To create a USB installation disk, you will need:
  • a 2 GB USB flash drive. Files on this USB disk will be erased, so previously backup your documents. Make sure this USB disk is properly formatted and mounted.
  • an Ubuntu ISO file (see GettingUbuntu to download it)

 Creating Bootable USB drive from Ubuntu

  • Insert and mount the USB drive. Inserting the USB drive should auto-mount it.
  • Start usb-creator. (K-Menu-->Applications-->System-->Startup Disk Creator (Kubuntu). If it is not there, then you can install it using the Synaptic Package Manager or Ubuntu Software Center)
  • in the top pane of usb-creator, pick the .iso file that you downloaded.
  • if the .iso file isn't listed, click "Other" to locate and select the .iso file that you downloaded.
  • Alternately, if you have a CD or DVD-ROM with the Ubuntu version you want to install on the USB flash drive, insert it in your CD-ROM drive and usb-creator can use that.
  • It is not necessary to erase the USB flash drive, however it is advisable that you do so.
  • Select the first bootable partition on the USB device as the disk to use
  • The bootable partition should be formatted as either a FAT16 or FAT32 filesystem. This is the default for most USB flash drives. 

Creating Bootable USB drive fromWindows

Download and use Linux Live Usb Creator.
Once you have usb-creator.exe, run it and follow the same steps as described for Linux (point it at your .iso file or your Ubuntu CD-ROM, point it at your USB flash drive, make sure you have the right device selected, then "Make Startup Disk").
  • Instead of usb-creator.exe you can use Unetbootin to create a bootable USB flash drive.
  • You won't be able to select the USB flash drive if it wasn't formatted in a way that Windows can see it. You may have to format it using the FAT32 file system
UnetBootin: After downloading Unetbootin from the link provided above, run the file, select an ISO file or a distribution to download, select a target drive (USB Drive or Hard Disk), then reboot once done.Select the USB drive as your boot device.
