I've got a functional MS-DOS 7.1 on a pendrive. It works on many machines with different chipsets, just as I've planned.

I'm having problems with building the same content of that pendrive in VirtualBox.

Is there any way to make VirtualBox boot from a pendrive?

So far I could only tell VB to boot from floppies (aka removable media) and mount the pendrive as a floppy, but that won't do. I'm getting a I/O disk error in VB while attempting to boot.

No way at this time.
