Although it is possible that you are correct, most "upgrades" of
MS-DOS have simply checked to see if a previous version of MS-DOS or
DR-DOS or PC-DOS or any version of OS/2 (!) existed before proceeding.
If they checked anything.

Create a boot disk. Copy the file "sys.com" to it. That is all you
need to install MS-DOS onto a clean hard drive: boot the new machine
from floppy and use sys to install the system files. Any upgrade
edition will then (almost certainly) be willing to install itself on
the hard drive.

And that assumes the upgrade edition actually checks before
installing.

An unnecessary note: I am assuming here that you are contemplating a
legitimate scenario, such as a disaster wiping your hard disk, or a
hard disk upgrade, or the replacement of your present machine by
another. You almost certainly have a Single-User license for whichever
version you use, which restricts you to using it on only one machine
(and may or may not address transferring it from one machine to
another).
