Run the below commands: sudo apt-get install syslinux mtools My USB partition is /dev/sdd1 enter lsblk to see what's yours.

Next, you need the ldlinux.sys file in your USB flash drive to make the USB bootable. Let's assume that it was mounted in /media/xxx/.Ĭopy all files from /media/iso/ to your mounted USB flash drive by running the below command (make sure to include the dot): cp -a /media/iso/. Your drive may be automatically mounted inside /media/. Sudo mount -o loop /path/to/ubuntu.iso /media/iso Then mount the ubuntu.iso file with the below commands in terminal: sudo mkdir /media/iso/ Place the ubuntu.iso file in any hard disk partition. If you do that, there will be confusion because there are pairs of identical partitions and file systems, and the boot system may choose to use them and write to them in a way, that both get damaged, so that they will no longer work.Creating a bootable Ubuntu USB flash drive from terminal Never boot the computer with both the original drive and a cloned copy of it connected at the same time.So, get an extra drive with at least the same size as the original drive, and use the imaging tool to restore from the image to that drive and test that the computer works as expected when the original drive is replaced by this new drive.

Otherwise you cannot be sure that the image can really be restored, and it might be too late when the original drive fails.

It is a good idea to check that you can restore from the image to a new drive.

(I must admit that Disks is easier to use.) Relevant advice for every method and tool, that you use for backup. I have used Clonezilla for years, and I am still using the 'Beginner Mode', which makes it fairly easy to do the correct thing every time. This means that Clonezilla will be faster than a crude cloning tool like Disks, and the image will be smaller too. It will also skip swap partitions and unallocated drive space, but the boot sectors and partition table are copied (to separate small files in the Clonezilla image directory).

Clonezilla is smart enough to only copy used blocks in the file systems, and skip free blocks.

But I prefer to create an image (in this case a directory with a set of files, where the big files are compressed).

You can clone directly to a new drive with at least the same size (not one single byte smaller).

Boot into it and let the menu system guide you through the process.

Download the stable iso file and create a USB boot drive.

ClonezillaĪn alternative tool, that I use is Clonezilla. And it is easy to use in a correct way according to the instructions by C.S.Cameron. I can confirm that it works to use Disks alias gnome-disks for this purpose.
