An MS-DOS start up disk is useful when you need to access DOS without booting into Windows XP. The procedure is relatively painless, although, it should be noted that  the start up disk will only allow you to boot to the MS-DOS 'A' prompt. The start up disk does not contain any other tools

2/ Click the Start button

3/ From the Start menu click My Computer
