Help putting Win 7 upgrade version on new system build

[nightlytoast]

I just got my computer up and running today.YAY
My next step is to install win 7 on it. So i got win 7 pro 64 bit through digital river with a sweet student discount and also a back up disc that came in the mail. I have noticed that it says upgrade on it though. I have been hearing and being told so many different things that i can not tell what is true.
Please only post an answer if you are certain it is correct
Thank you and with that being said here are my questions

Questions:
Could someone please explain to me what i am exactly supposed to do with the backup disc?
Can i use this on a new computer, ie one without any os on it already?

A friend referred me to this site. It sounds very confusing and i am not very tech savvy when it comes to things like this. Will i need to install it onto a diff computer in order to do this bootable upgrade? does the back up disc come into play? Could someone please explain the instructions in a very simplistic way.

Ya, next time know what your buying before you pay for it. If you done your research like you claim, you know the answer already.

Install Vista, then do your upgrade.

is the backup disc from an OEM system? Is it the same as your machine?

Thanks for replies.
Called MS and they gave me the clean install version for same price and returned other one, so i don't need to go through the hassle of burning it and doing all that.
