Win32DiskImager - Ubuntu Wiki
Win32DiskImager is a Windows program that creates a bootable USB drive from a Linux ISO file. Apparently unetbootin has some bugs with latest openSuse distributions and people on forums advise using this. I can confirm having trouble using unetbootin-created image on the machine where I want to install Linux. However, the same thing worked in a VM when I was testing the USB stick. Weird.
And, yay! I can confirm that creating a bootable openSuse 11.3 USB with Win32DiskImager works perfectly!!!
