The VxWorks is a real time operating system that was developed by Wind River Systems. The operating system was first released in 1987. The operating system is designed for use in embedded systems.
It is not hard to load operating systems software but first you must make sure the old operating system has been removed then use the software discs you have to being loading the new system.
DOS meaning Disc Operating System
The first operating systems were nothing like modern operating systems and were usually called batch monitors, because all they did was automatically ran jobs sequentially in batch mode. Computers of the time had no interactive mode of operation. Computer companies did not supply software of any kind with their machines, so it was usually up to the user (company, university, government office) to write all their own software. The first batch monitor/operating system was done in 1954 by MIT for their UNIVAC 1103. General Motors did one in 1955 for their IBM 701.The first computer to come from the manufacturer with an operating system already installed is a different question.
By operating systems, I am assuming you are referring to computer operating systems. In order to get a good idea of what an operating system entails, I would first recommend that you read the definition at wikipedia. There is also some great information at www.howstuffworks.com.
There were operating systems from Microsoft before Windows was first released in 1981. Known as MS-DOS 1.0, this operating system was provided with the IBM Personal Computer.
Basic Machine, in computer parlance, means a computer without its operating system. Modern operating systems evolved through various stages, from elementary to the present day complex, highly sensitive real-time systems. In the very first stage of computing there was nothing like an Operating System at all. Programs were fed to the computer system directly using machine language by the programmers without any system software support. This approach is termed the "Bare Machine" approach in the development of operating systems.
If one or of the operating systems does not cooperate well with dual-booting (such as Windows with a Linux distribution), then you should install the troublesome operating system first. If both are well-behaved (such as two Linux distributions) then it does not generally matter.

Most first generation computers had no operating system. When they did, it was usually just something called a Batch Monitor, all it did was sequence through several jobs one at a time that had been submitted in a batch. The computer companies saw no need for any form of operating system, so the machine's users had to write them all themselves. It was not until the second generation computer that computer companies supplied operating systems for their computers and the earliest of these were simply adaptations of operating systems written by users of first generation computers with a few extensions.
