ISO to USB on Kubuntu

I'm running kubuntu 15.04 and I want to make bootable usb stick from an ISO file, how can I do that? I tried this: How do I make a bootable USB stick from an ISO image? I also tried running UUI by wine (it didn't detect my usb stick)

Use dd.

 sudo dd if=input.iso of=/dev/sdx

where input.iso is the input file and /dev/sdx is the USB device you're writing to. This method is fast and has never failed me. Note: that the 'x' depends on the actual device the usb mounts as.

Install unetbootin

sudo apt-get install unetbootin

1. plug in a USB drive
2. Delete all partitions on the USB drive
3. create a fat32 partition
4. mount the flash drive

open up a terminal and start unetbootin

sudo unetbootin

1. select disk image
2. choice you iso
3. select you flash drive
4. then click ok

wait for that to be done and you have your self a bootable usb stick.
