[lubuntu] Unetbootin & Lubuntu 12.10

Hello,
I have a question I hope someone can help me with. I would like to install Lubuntu 12.10 on my computer (not Live CD, I want to install it on my HD as the only operating system).

I downloaded the Lubuntu 12.10 ISO file, and I downloaded the latest version on Unetbootin so I could install from USB Flash drive instead of CD ROM.

But Unetbootin doesn't list Lubuntu 12.10 on its "version" drop down menu. It has 12.04 but not 12.10. So does that mean I can't use Unetbootin?

Is there a work-around, or can somebody recommend another program to write an ISO to a USB Flash drive?

Thanks for any help.
