Tri-Head PCI card with Altera gpu(?)

I have downloaded and installed MaxPlus II 10.2 student, and the Baseline. However, when trying to get the license, it asks for the Hard Disk Volume Serial number. I looked it up (so I wouldn't have to ask what it is) but I have no clue how to retrieve it. The only stuff I found on how to do it, is with some string of parameters that I don't know. I am still below Novice at all this, and just trying to get going. Can anyone direct me on how to retrieve this Serial number?
