I'm on windows.

I'm trying DragonflyBSD operating system. as you can see here: there are two kinds of images CD (.iso) and USB (.img) files available for download.

I downloaded *.iso and using UNetbootin to make a bootable USB stick. But its taking hell lot of time. Its been 2 hours and its just 50% done(9k of 18k files). I'm really pissed off now!

I used *.iso because I didn't know how to deal with *.img files. Will it be quick *.img file? How to use it to make bootable USB?

what does windows have to do with this? – user33788 May 21 '10 at 2:38
@smoknheap : most of the articles & tutorials on net are giving me a solution but from linux. I don't have linux. I'm on windows. – claws May 21 '10 at 3:25

Try Win32 Disk Imager or the other solution for Windows in the linked article. The article is for Ubuntu but the process of writing an img file to a USB stick is the same.
