Yes, the fdisk program acts that way. Adding ":" after the
drive letter (as a capital letter) is a thing you usually
see in any documentation, like "this erases you C: drive"
or "check floppy in A: and B: to make sure they are present".

Okay, then "Laufwerk" and "drive" are corresponding correctly.
Then it's a "logical drive inside an extended DOS partition".
I will remember this, thanks for checking!

I'm _sure_ it was a 20MB hard disk, maybe just a typo? :-)

You should have DOS in caps always, as in "primary DOS partition".

And it is possible to have a bootable system without a primary
DOS partition? I hardly can imagine that - but don't bet on
my opinion, I've NEVER used any "Windows", so I'm honestly
A typical "multi-drive" setting would contain a primary DOS
partition C:, and an extended DOS partition containing the
logical drives D:, E: and F: (for your 4-drive example).

The program's name is "disklabel" or "bsdlabel" respectively.

I'm sure you wanted to say 20MB - megaBytes. :-)

The program "boot0cfg" does this.
