Serial Port

I am a beginner at this, so please tell me what to do in words that are easy to understand. I was trying to run a simple program on my new arduino uno, and the program verifies it okay, but when I try to upload it, it says "Problem uploading to board. See for suggestions." I went to the website, and the solution to my problem was to do something in my tools/serial port. I went to my tools bar, but there was no serial port. How do I install or somehow get that on my arduino programmer?

On the toolbar there is a "Tools" menu. Select "Serial Port" and select the COM port your Arduino
is connected to.

If your port does not appear, you need to load the driver or whatever else on your PC.
