This question already has an answer here:
I downloaded a Windows ISO file, and I want to install it on a USB flash drive through Ubuntu. However I can't seem to get unetbootin to pop up. I've tried everything. I also tried using another program and got it to write it to the USB, however it took 12 hours for a 3gb file? When I finally rebooted, and selected load from flash drive, it would just start loading up Ubuntu again.
I just want a copy of Windows on my new computer, but I need to either get unetbootin to work, or else get an alternative to work.
