How to Create an MS-DOS Startup Disk With a USB Flash Drive

Creating a DOS startup disk on a USB drive means that you will be able to boot any computer you encounter into MS-DOS quickly and efficiently. This is necessary when making changes to the operating system (such as reinstallations) or where you are attempting to avoid loading all of the device drivers associated with the system. Making a USB boot key can be done rather quickly, but it requires the use of external programs.
