    Create Bootable DOS floppy image

    Hi,
    I am trying to make bootable floppy image files for use in Virtualbox. I have the files from the the MS-DOS floppies on my computer.

    I have tried this:
    Code:
    dd if=/dev/zero of=floppy.img bs=512 count=2880
    mkdosfs floppy.img
    sudo mkdir /media/image
    sudo mount -o loop floppy.img /media/image
    sudo nautilus /media/image
    Copied the files to the mount, then
    Code:
    sudo umount -l /media/image
    Then I tried to start my DOS Virtualmachine in Virtualbox.
    But it stops with error: "This is not a bootable disk"
    What's wrong with the image file?
