Help! How can I enter pure DOS mode under Win2000? - China DOS Union Forum

My computer has WIN2000xx installed. Please tell me, without using the CD-ROM drive, floppy drive, or a flash drive to make a boot disk, how can I enter pure DOS after restarting? (Since drive C is in NTFS format, if I install DOS, can it be installed on drive F, which is FAT32?) Are there any other better methods?

Here is one method I found online, but I don't know how to do it, and I can't find the files made by the original author anymore:

“Anyone who has used Drive Image 5 knows that it only starts working after a reboot, and on an NT-kernel system
this is very obvious. Since PQDI cannot run under the NT kernel, then after reboot it naturally enters a system
where it can run
—DOS. But many people have no other system installed besides 2000/XP, so where does this DOS come from?

　　According to analysis, it has a program that can boot the system into a virtual floppy disk ( skipping a lot
of explanation here ). What this virtual floppy actually uses is a VFD-format image ( skipping more ),
and another program bundled with it, VFeditor.exe, which is
the PowerQuest OEM version of WinImage, is used to edit what it uses. That is where my inspiration came from.

　　Since it can boot the system into a virtual floppy, then from then on it can replace later boot disks. When the local machine
cannot use a floppy drive/CD-ROM drive for some reason,
such as an ultra-thin laptop, when you don't happen to have a CD or floppy with you,
but still need to boot into DOS to do certain
xx operations ( such as reinstalling the system, killing viruses ), it becomes very convenient ( because it seems there are no viruses that can infect VFD images, so
its safety is just like a CDRW )

　在XIAMI's FTP, upload/by@vsj/vfd.exe is it. If your system kernel is NT, and you're interested,
go get it and try it. Remember that if it runs successfully it will automatically reboot,
and then you will see the effect of this temporary version”

This kind of image boot should be based on the 2000 system, right? Then once the system has a problem, if you want to rely on this to reinstall, that's no different from a fool's dream.... However, for doing antivirus and the like... maybe it can work. But DOS doesn't recognize NTFS partitions. After you load ntfsdos, memory gets eaten up badly. Can you still run large software like kv, nv? 。。。。。。。。。。。。。。。。。。But the technology itself is still quite interesting.
