Navigate to the /media/xxx mount folder and rename the isolinux directory to syslinux. 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. So the target needs to be /dev/sdc and not /dev/sdc For me it was /dev/sdb.Ĭreating a bootable Ubuntu USB flash drive from terminal This method is fast and has never failed me.ĮDIT: for those on a Mac ending up here, use lowercase for bs=4m: sudo dd if=inputfile.img of=/dev/disk bs=4m & syncĮDIT: If USB drive does not boot (this happened to me), it is because the target is a particular partition on the drive instead of the drive. Where input.iso is the input file, and /dev/sd is the USB device you're writing to (run lsblk to see all drives to find out what is for your USB). Then, next (this is a destructive command and wipes the entire USB drive with the contents of the iso, so be careful): sudo dd bs=4M if=path/to/input.iso of=/dev/sd conv=fdatasync status=progress ├─sdb1 8:17 1 1.6G 0 part /media/username/usb volume name It will look something like sdb 8:16 1 14.9G 0 disk Where is a letter followed by a number, look it up by running lsblk.
