You DO realize that by doing it that way you're going to have to BOOT TO ONE OS OR THE OTHER at a time.
This means that you will only have access to those files that you CREATE on that OS/partition at a time. (I.e. you will NOT be able to "share" files, etc. between the two OS installations.) Likewise you may have to install applications on BOTH partitions as needed.
It's actually not that hard to do, just screwy because of the constant duplication of stuff, tho. (FYI: WHen I tried this I made a third partition for "shared data" that was visible to BOTH OSs. This allowed me to access the data from either OS, but you have to be sure that the data types your dealing with are "universal" in format, and can be understood by both OSs. Worst part is: YOU have to figure that out, and you have to do it pretty-much via trial and error....)
I'm PMing you a Google search list with scads of info about "dual booting."
P.S.: This ("dual booting") is basically how one goes about having Windows and Linux running on one computer at the same time, BTW....
