FreeDOS has at least three "fdisk" programs, so maybe FD fdisk [sic]
can't do it, but maybe try the others (e.g. xfdisk or spfdisk):

Actually, what version of FD fdisk are you using? IIRC, it wasn't
quite finalized, so there's some confusion between 1.2 and 1.3 series.
So maybe try whatever other version you're not already using:

Or would maybe Ranish Partition Manager work??

I did already suggest using floppy to him, but he didn't seem to
acknowledge or want it. Dunno.

RUFFIDEA is too old, similarly BARE_DOS (although I still have them
available). I don't know offhand where Brezel is. And most other such
floppy images are all old, too (e.g. ODIN, Balder, Joris-8086, etc).
But ....

This is a recent effort by me and meant to be a minimal (but easy and
convenient) starting point. By default, it comes as a 1.44 MB 3.5"
floppy .img (roughly only half filled) with a few essentials (FD
fdisk, format, sys).


The idea is that you can modify it under modern VM (e.g. VBox or QEMU)
before writing it to physical floppy, if needed. GNU Mtools (under
Linux or similar) would also allow that, among various other methods
(e.g. mount loopback or whatever).

Win7 still has the ability to "make system floppy", which is a
slimmed-down, emergency, minimal MS-DOS image. RUFUS can use this, if
found. However, allegedly Win10 doesn't have that anymore. IIRC, in
recent years MSDN used to still sell full MS-DOS 6.x, but I'm not sure
anymore. (And there are still other DOSes still available online, too,
e.g. DR-DOS or ROM DOS.)

I suggest you try a different FDISK program. For that matter, you
could also maybe use GParted or cfdisk or whatever on Linux (or BSD or
...) to do it. Especially since you imply that Linux works fully on
that type of machine.

You may also need this:


Or "maybe" this will help??

Or why don't you install FreeDOS under VM to raw disk image, and then
dd it to the physical hard drive while under Linux. Then it should
boot correctly, right?
