dual os

Hey guys (guys is used loosely, I do not mean to trigger anyone:lol:), I am on a tight budget as the title explains. I want a future proof build for later upgrades when I have a extra cash on me. I would like for the build to run dual OS for some casual gaming and video/photo editing. Thanks.

Hi, i know a thing or two in installing a fresh copy of windows in devices, but i'm a total newbie when it comes to MAC. i googled my laptop, LENOVO G470 (20078 model) and it seems like it is able to run Mac OS X Mountain Lion, and i wish to install both mac os x and windows 8 in my laptop...
