Don't listen to him, OP.

It installs DOS on whichever drive you tell it to.

Actually if you run it in Windows it won't, because Windows won't let you overwrite the hard disk, but it might let you do it to a floppy disk.

What he said.

Or, in other words, it makes the drive targeted bootable in MS-DOS and copies the core system files to it. (Usually command.com, and a few other files, varies with version.)

Modern Windows won't let you do it to C: (if it's available at all). On less modern Windows OS drives, it won't have any effect, as it's already been done.

Fine on a floppy. It won't necessarily make a modern hard drive or USB stick bootable.
