I am trying to make bootable USB using Rufus.
I downloaded Rufus and selected the downloaded ISO but nothing happens.
As per the instructions here. I should have been prompted to download syslinux SW,
What am I missing?
Rufus author here. You will only be asked to download the Syslinux files if they don't already exist. If you used an ISO with the same version of Syslinux, Rufus will not ask you to download them again. In other words, you can safely ignore the part where Rufus asks you to download extra files, if it doesn't prompt you to.
Summary: That behaviour is normal and not an error, just an oversight in the tutorial.
Note, this doesn't seem to work with UEFI and seems to only work on a legacy or BIOS system.
Try using http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/ instead. Click on "Browse" to select the iso file you downloaded earlier.
If you need to re-download the iso, you can click here to download the 64 bit version.

This used to be the recommended method
Use Universal USB Installer instead: Link
Format the USB drive first, then use Rufus
Change the device name to Rufus, volume name nothing, remove it, then click "Format"
