I generally prefer Windows XP, but sadly this came out of support earlier this year so we all have to use Windows 7, 8 or Mac osx :)
Yes You Can! :D
Unfortunately you cannot run Mac OS X games on windows.
It depends on what your criteria is and what you are looking for in a computer.
There is no "the" operating system. There are LOTS of different ones available. Windows XP, Windows Vista Linux Mac OSX and much more... There is no "the" operating system. There are LOTS of different ones available. Windows XP, Windows Vista Linux Mac OSX and much more...
yes but only on a virtual version of mac osx
Hard drives for windows and OSX vary in size and model, check or ask about your computer brand. You can also check in My Computer (for Windows) or Macintosh Disk (for Mac OSX).
To run windows XP and Mac OSX they recommend a minimum of 128MB of RAM. However for optimal performance they recommend 256MD for windows XP and 512MB for Mac OSX
Windows 7 Ubuntu 10.10 Mac OSX Lion
MS Windows, MAC OSX, and GNU/Linux.
No, not without OSx already installed.
Mac is computer software that isn't compatible on Windows. You shall have to create a hackintosh (building a computer with specific parts) to be able to run Mac osx. It does work the other way around. Mac can run Windows.
You can try to install Windows on a MAC, but it would be very difficult since Macs are not designed for windows. Their are some programs out their that you can buy that allow you to just run windows right from your Mac OSx desktop.
