When I dual boot, I am confused about how my hard-drives are set up. How much space do I have? Where are my documents? Where are program files stored? I am comfortable with Windows 10, now, and this took a while, … with “OneDrive” and Quick access Libraries, etc. So, I would rather have a real machine than a virtual machine.
Also, maybe even more important, if Linux is running in a Virtual machine, on top of Windows, I fear it will cause problems talking to hardware and peripherals. Maybe this is not a realistic fear, but… I think it’s grounded. I don’t want to have any trouble printing, or scanning, or burning DVDs on an external DVD drive. Or accessing my camera, or digital microscope, or Arduino development boards. One operating system was meant to run One machine. “KISS”, Keep It Simple and Stupid.
