I've got a USB floppy drive and those good old MS-DOS disks How can I install MS-DOS in a virtual machine using those floppies? I have to to some Assembler coding and want to do that in an MS-DOS environment.
you should create a new VM using a 'Custom' mode.
Then open 'Configuration Editor' of your new VM, select 'Options' -> 'Booting' tab -> check 'Floppy, hard Disk, CD-Rom'.
After that configure the 'Floppy' tab and start your VM.
unfortunately the VM doesn't boot up correctly using these settings. It says that it's trying to access a floppy disk but can't find any. The LED from my external USB floppy drive doesn't confirm what the VM's saying.
Boot from floppy drive...
Non-System disk or disk error
Replace and press any key when ready
here are the two screenshots you requested. Before I made the screenshots the floppy symbol in the Finder looked different from now, don't know why. The symbol before was a floppy disk.
