so you are saying how to run two PC OS together, right? I notice you have the OSX tag, that's why I thought you want to talk about hackintosh. – deddebme Aug 22 '09 at 3:57

You can use a virtual machine to do this, and allow it to operate in seamless mode.

VirtualBox is a nice cross-platform, free application which allows you to do this. You can emulate nearly every operating system under one-another. The full list of compatible guest operating systems can be found here.

The following is Mac OS X emulating Windows XP in seamless mode:

And the following is Mac OS X again, but emulating Mandriva Linux:

While you can use seamless mode, I find it much easier to just switch between them using Fullscreen mode... Although this depends largely on the purpose of the virtual machine.

And VirtualBox is free, too. – Thilo Aug 21 '09 at 13:40
If you don't mind paying, or want support (but don't expect much support from Parallels - their support sucks), the commercial alternatives are: <a href="">VMWare</a>; (more stable and dependable), and <a href="">Parallels Desktop</a> (very fast and tons of features, but more fragile and terrible support). – The Tentacle Aug 21 '09 at 15:50

can i run windows xp and windows 2003 with the help of this application – Himjones Aug 22 '09 at 8:53
Yes you can. You can install either OS first, then emulate the other one by installing it into a virtual machine. Then start up the virtual machine, and set it to "Seamless Mode". – Breakthrough Aug 23 '09 at 6:09

You cannot use use two Operating systems at the exact same time without some virtual environment (e.g. a hypervisor).

You can install two and use them independently of each other, however. For example, you can do a clean install of Windows XP and partition your hard drive into two partitions during the install. The Install Windows Vista or Windows 7 or some flavor of Linux to the second partition. This will allow you to choose which OS to start during each boot.
