Creating a bootable MS-DOS startup disk allows you to access your computer and its files externally. This can be especially helpful if you are experiencing severe virus and system issues within Windows. Creating a USB startup disk requires that you format your external USB drive to be used as a boot-up disk. The formatting process deletes all files and data associated with your USB drive. Use a blank USB drive, or back up the files on your USB flash drive before beginning the formatting process.
