What's the exact message, "directory x doesn't exist" ?
Also I don't know if it's a typo while writing this post but there shouldn't be a space between D:\ and dell

What are you mounting exactly? A directory in an HDD partition or an image?

BTW, this thread should be moved into the DOSBox section of the forum.

How do I move this to dos section of this web forum? I’m new to this. I am trying to program a Motorola GM300 transceiver. It requires Dos. But the only old computer I have is a Dell with XP. So that’s why I need dosbox. The help menus says to get C to be the D directory. That’s where my first problem starts. It can’t find D:\

We can't, that message was for the mods. 😉

DOSBox is not suited for non-gaming stuff. The old computer can still boot to real DOS with a USB memory stick, floppy or CD drive for this kind of stuff.

Do you actually have a real physical HDD partition that uses the D drive on the computer? If not, then it can't obviously find D: in your computer.

If it is a CD/DVD drive, then add "-t cdrom" after the rest of the MOUNT command.

1MOUNT C D:\ -t cdrom
