Run Windows, Mac, and Linux Side by Side and Pain-Free with VirtualBox

Now you might need to work on multiple Os for many reasons. I needed to work on Xp cause turbo C doesn't work good with win & or vista. Normally people would suggest Dual-boot but you can eliminate that with using Virtual box

  I'll show you how to easily install new operating systems (including Mac OS X and Linux) and optimize your installation with shared folders and software to help your virtual machines communicate with your main OS. We'll also do a little extra work to get the newest release of Snow Leopard to play nice, even though it's not fully supported yet. Although we're using Windows 7 64-bit as our base OS, VirtualBox runs on nearly any OS, and these tips and tricks are applicable to any serious VirtualBox setup.

Why Virtualize?

Using virtualized operating systems presents all sorts of opportunities. You don't have to leave your primary and favored operating system to use tools found only in another operating system; you can run a copy of your current operating system to try out new tweaks, tricks, and software to ensure everything works well; you can test new software or browse in an entirely sandboxed OS. One of the great perks of running multiple operating systems in virtualization come with multiple monitors, you can spread out almost as though you had separate computers hooked up to the same keyboard and mouse.

What You'll Need?

You're most likely using a machine right now that would easily support at least one other operating system in virtualization, but likely more. . It has an Intel quadcore processor, 8GB of RAM, and a basic graphics card with 256MB of RAM. The parts weren't cutting edge when we bought them—all of them were selected because they were on sale—and they're certainly not cutting edge now. With those specs, the machine easily runs Ubuntu, OS X Snow Leopard, and Windows 7 32-bit simultaneously—powered by a core OS of Windows 7-64 bit—without any problems. If you've got a reasonably new system with a good amount of RAM, you should be just fine.
