(For some reason, I actually need to click something in the window before the option becomes available, not sure why.) 4) Browse to your VHD file that you created and click OK. 3) From the 'Action' pulldown menu on top, choose 'Attach VHD'. 2) Open your 'create and format hard disk partitions' Windows tool (or run 'diskmgmt.exe'). (As in, you could wipe entire hard drives.) Ok, so to mount your fancy new virtual hard drive with DOS on it in Windows: 1) Shut down your DOS virtual machine. The following may cause ACTUAL data loss on your ACTUAL host computer. !! IMPORTANT !!: PLEASE do not continue if you're not familiar with disk management, partitions etc. Works exactly the same from our perspective, only VHD you can directly mount in Windows (at least in 10+) and use as a normal drive. All you need to do is: in step 3, at 'Choose a virtual hard drive format.' choose VHD instead of VDI. For directly copying to/from your emulated DOS drive, you *don't* have to mess with third party tools that emulate floppy drives or CD-ROMS or anything. So, for everyone still here in 2022 or later.

Go to the 'Network' tab and choose 'Bridged Adapter', then choose your network adapter. Next go to the 'Audio' page and make sure it is set to SoundBlaster 16. In the windows that pops up, click 'Leave Empty'.

Next go to the 'Storage' page and click on the 'Add Controller' button. I used 8 MB, but you can use pretty much any amount above the red. Next go to the 'Display' page and set the amount of video memory. Go to the 'System' page and click on the 'Acceleration' tab. (I renamed mine DOS because I already had one nme DOS 6.22) Right click on the virtual machine you just created and click settings.
