A computer that can boot one of several operating systems by means of a startup menu. An example is a machine on which Windows 98 and then Windows NT has been installed. The user can utilize the Windows NT boot loader menu to choose which operating system to run at startup.
Windows NT supports dual booting with other operating systems, but this is neither recommended nor supported by Microsoft. Dual boot systems are typically used in hobbyist and test networks in which a variety of operating systems are used to test different networking functions, or when the number of available machines is fewer than needed to perform the tasks.
The Windows NT boot loader menu can include up to 10 operating systems.
