Re: Have some newb Q's. Need help with partition and install
I agree completely with Ian - if you are new to Ubuntu, just let Ubuntu do its own default partitioning.
Also, yes your existing files will be available and usable, especially music, videos, photos and Microsoft Office documents.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
