Hrmm? MS-DOS doesn't *really* exist in newer versions of windows, so what do you mean? In 9x the Windows GUI is basically running on top of DOS, so your questions doesn't make alot of sense..

Which every OS has it's code in the Master Boot record will be loaded when the system starts. There are programs like System Commander that will allow you to load many different OS's and when you start your computer, it asks you which one you want to boot. This is called Dual Booting or Multiple Booting.

You can also load new OS's inside Virtual Machines with programs like VMWare. This is my choice as a developer, since you don't have to reboot to test code on other platforms. Plus, if you code takes the system down, it will only kill the Virtual Machine and not your development platform.

Hope this answers your questions
