Then you create config.sys and autoexec.bat files on the C drive. You can then remove the floppy and reboot, it will boot from the hard drive. You first need to create partitions on the virtual C: drive using FDISK, and then format the C: drive using the command 'format C: /s' (the /s makes the drive bootable).

a bootable floppy containing DOS system tools including FDISK.EXE and FORMAT.COM). You need to boot from a system floppy (i.e. It's easy enough provided you didn't make the hard disk too large (my own DOS 6.22 VM has a 512 MB hard drive). I assume you might be asking how to get it to boot from hard disk?

Well, if you booted from floppy then it's already a working DOS VM.

Is it possible to make a DOS VM with 3 DOS-floppy-images as well? How? Joe890 wrote:I used an image of a very basic DOS622 floppy.

Or, just boot from the floppy but then run setup from the CD: the boot disk you find online will include CD drivers. That floppy image can be mounted in any other VM (once you add a floppy drive anyway), then you can copy from a shared folder onto the floppy image. If I was you I would look online for a boot floppy of the correct version of DOS. On the subject of tools, I don't know of one (which doesn't mean it won't exist) that can create floppy images from a group of files, also the first floppy in the set would have to be bootable. It must not be compressed nor have a header imposed by some tool. A raw image of a 1.44MB floppy usable in VirtualBox should be exactly 1,474,560 bytes. The MS developer CD probably has folders called DISK1 and DISK2 etc, so that's what each of the floppy images needs to contain.īy the way, VirtualBox floppy images are raw, so don't be misled into using some crazy tool just because it reuses the '.img' extension. You will need either physical floppies and a physical floppy drive, or else you'll need floppy disk images.
