When I try to create bootable USB stick for Ubuntu 16.04 LTS, after conversion one or many of the following happen

  1. No files are seen in the flash drive.
  2. I get 'the file is corrupt' message.
  3. The flash drive space remains occupied
  4. Flash drive isn't recognized by the computer

I have tried using different, completely new, undamaged flash drives. Upon using Rufus I get a message, "Access denied."

Please guide me resolve this issue.

Thanks for the help.

  • What do you mean by convert? You should be able to write a iso image to a usb drive without any problems. – spacelander Aug 14 '17 at 11:16
  • Also, are you trying to write the usb drive from a windows or a Linux machine? – spacelander Aug 14 '17 at 11:18
  • Mint is off topic here. – Organic Marble Aug 14 '17 at 11:39
  • Which ISO files do you want to boot from a USB drive specifically? The procedure may vary depending on the ISO layout and bootloader type among others. – David Foerster Aug 15 '17 at 15:35
  • Ubuntu 16.04 LTS. I couldn't make USB stick. So tried Linux Mint. Same issue faced. – mohinip Aug 16 '17 at 8:03

Most linux iso files are hybrid iso files. It means that they can be cloned to a USB pendrive and the USB pendrive will be a bootable drive (live drive or install drive).

  • In current versions of Ubuntu you can use Disks alias gnome-disks,
  • in Ubuntu 16.04 LTS and newer versions you can also use the Startup Disk Creator to clone from the iso file to a USB pendrive,
  • You can install mkusb in most current linux distros,

to clone from the iso file to a USB pendrive.

from the iso file to a USB pendrive. The cloning process is straight-forward and therefore very reliable.

But Rufus has a good reputation, so I don't know why it was failing for you. Please check with md5sum that the iso file was downloaded correctly. See this link.
