The DOS operating system is directly loaded into the memory and runs when the computer is turned on. The computer directly enters the DOS black and white screen interface, and uses DOS commands to restore the system such as GHOST, or reinstall the operating system, restore the operating system, and perform anti-virus operations. In the Internet where viruses are rampant In the era, system maintainers often had to boot the computer into DOS. For Windows 98, you can directly press F8 to enter DOS during startup. For Windows 2000 (windows xp or Windows 2003), can you directly boot into DOS without using a floppy disk or CD? How about booting from the hard disk to DOS? Now, let’s quickly create your own dual system so that Windows 2000 (windows xp or windows 2003) can boot directly from the hard disk to DOS.

Method 1: New installation

If your Windows 2000 (Windows C:" (assuming it is installed on the C partition) format the system as a startup disk with a DOS boot file. After the formatting is completed, then install the Windows 2000 (Windows The dual system of (windows xp or windows 2003) + DOS has been successfully created.

Method 2: Add DOS

Perhaps, your Windows 2000 (Windows XP or Windows 2003) system has already been installed; perhaps, you do not want your Windows 2000 (windows The software vFloppy——to realize the dual system of windows 2000 (windows xp or windows 2003) + DOS. VFloppy download: Click to download.

It is a green software. After decompression, run vFloppy.exe to open the program. The main interface is shown in Figure 1. Click the "Select the path to the image file" button, then select BOOTDISK.img or NTFS.img, and click the [Apply] button to complete the Windows 2000 (windows xp or windows 2003) + DOS dual system.

As for uninstalling the virtual boot floppy disk (actually there is no uninstallation, because it is not installed), you only need to open the Boot.ini file in the root directory of the system partition (as shown in Figure 2), and change the corresponding startup menu Delete the item (for example: C: BOOTBOOTDISK.bin="Boot from virtual boot floppy disk"), or change "timeout=30" to "timeout=0".

Generally speaking, computers can only recognize machine instructions. However, in fact, users do not directly use machine instructions to control the computer. Instead, they manage and use the computer through a set of powerful commands provided by the operating system. Therefore, it is quite necessary to study this tutorial.
