I want to install MS-DOS, Windows 95, Windows 98, Windows 2000, Windows XP, and Windows 7 all on one computer, on a single 1 TB hard drive. First off, is this even possible? Will there be any compatibility issues? If it not possible, can it be done from multiple hard drives? Will there be any issues with my running these operating systems with modern computer components? Also could I run games from previous versions of windows in windows 7 if I had all of these installed, or would I actually need to load the particular version of windows for which a particular game was originally designed. I will be using the original installation discs for each system. Help appreciated.
