Hi, I'm currently in the works of buying parts to build my gaming PC, but have never touched an operating system before. I need to buy an OS for my PC, but I have a few questions before doing so. Firstly, I want to buy 8.1 students as a download. Now I currently don't own a PC so I can't buy it yet. I plan to use my friends PC to help out and download the OS. If I download the OS using his PC, will it try to install 8.1 onto his PC and override his current OS, or will the program just download without doing anything else? If it does the latter, then is it possible to just put it onto a flash drive? Or will we have no choice but to have it install 8.1 to his computer? I'm sorry if I didn't explain it right, I never thought about the OS until now. Will it be easier and better just to buy the disc?
