I want to make a bootable USB stick.

I run the UUI.

I see the instructions on this site: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows

Step 1 says: Select "Ubuntu Desktop Edition" from the dropdown list

Okay, so the actual title of the drop down box is: Select a "Linux Distribution" from the dropdown to put on your USB

I am pretty new to computers. 67 years old. Live alone. Bought my first computer 3 months ago. So I will have to assume that when the instructions say "Ubuntu Desktop Edition", that means the same thing as "Linux Distribution". Okay, No big leap there. So far, so good . . . . . . .

So I pick the very first selection: Ubuntu 13.10 Desktop i386

I'm not sure why there are so many choices, but I'm guessing I'm pretty safe with the first one. It's for a Toshiba Satellite laptop 64 bit Windows 7.

Okay, now for step 2:

The instructions say: Click 'Browse' and open the downloaded ISO file.

The message in the window just before the "Browse" button says: Browse to your ubuntu-13.10*desktop*i386.iso -->

Okay, so where's that file? So I click "Browse" and start looking for that file. It is nowhere to be found.

So where the heck is it?
