I am a new Linux user. I recently installed Debian stable 8 from Windows through unetbootin but now I would like to use Ubuntu. I have downloaded Ubuntu iso file. But I am not able to write it to USB as in Debian, I am unable to install unetbootin both from repository and direct download as nothing happens when I double click the unetbootin file even though it is marked executable. I tried various other command options, also searched on google but all solutions had some problems. Please advice me how to make my USB bootable with Ubuntu preferably with unetbootin.

  • don't know much about unetbootin but use rufus for windows instead or universal usb installer. Rufus is better in my opinion but universal usb installer has more widespread compatibility. (Source: Any google search with programs I mentions) – user175999 May 29 '15 at 10:04

The preferred way to make a bootable usb in debian is using dd. so:

sudo dd if=/path_to/ubuntu.iso of=/dev/usb-mount-point

will write the contents of ubuntu.iso file to usb-mount-point. You have to see where you have mounted the USB (you can use sudo fdisk -l to see (usually it will be /dev/sdb or /dev/sdc).

It is important to be absolutely sure of the mount point of usb before running the dd command.

  • You forgot to add a filename on the mounted directory e.g. of=/dev/usb-mount-point/Ubuntu.iso. I am not quite sure how dd handle a missing filename on the destination directory but I think it is clearer for all if a filename is stated. Cheers – Mike May 29 '15 at 11:30
  • @Mike you do not need to add a filename on mounted directory because we are writing the contents of .iso file to the mounted device directly. – Ron May 29 '15 at 15:44
  • It's not /dev/usb-mount-point but rather /dev/sd[letter] with "letter" being a single alphabet letter designating the USB drive. Try lsscsi tool (not installed by default) in order to identify the device. – EnzoR Jan 29 '16 at 8:00

The one and only supported way to "burn" an ISO image to a USB drive (memory stick) is the "USB Creator" tool aka "Startup Disk Creator".

It basically does some conversion and then copies the stuff onto the USB device. Be warned that the USB device content will be wiped as a result for the whole process!
