Currently, you are using Windows XP SP2, but you would like to add MS-DOS. Is there a way for Windows to present two options—Windows XP or DOS—every time you start your computer? This article will guide you through a simple method to achieve this.
First, copy the DOS boot files: Io.sys, Msdos.sys, Command.com, Config.sys, and Autoexec.bat to your C drive. Then, add the line C:=”DOS” to the Boot.ini file, for example:
[boot loader]
timeout=2
default=multi(0)disk(0)rdisk(0)partition(2)WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)WINDOWS=”Microsoft Windows XP” /fastdetect
C:=”DOS”
After this, each time you start your computer, an option will appear allowing you to boot into either DOS or Windows XP.
