- Insert the USB device, then open GParted.
- Select the USB device from the list near the upper-right corner of the GParted window and detect where it was mounted: /dev/sd[1 letter]. Mine was /dev/sdc.
- Make sure the USB device is unmounted (right-click and select unmount). Don't forget to format it to NTFS or VFAT.
- Open a Terminal window and navigate to the iso file you want to use. I used this line:
- The last step is to write this line:
sudo dd if=[UR .ISO] of=/dev/sd[THAT 1 LETTER]
# apt-get install syslinux
# isohybrid path/to/image.iso
# umount /media/usbdrive
Use dd to write the ISO image to the disk path. That's /dev/sde NOT /dev/sde1:
dd if=path/to/image.iso of=/dev/sde bs=1M
