If I buy a computer with FreeDos, I assume I can install Windows 10. I'd grab the Windows 10 installation media tool, and save it to USB? Then, restart the machine with FreeDos, booting from USB to install?
@MyDaftQuestions Yea, shouldn't be a problem at all. You would likely need another computer to download the install media though. I can't imagine FreeDOS would handle anything like that.
