No Windows key, I'll run Linux and use a VM with MS OS. I ran XUbuntu on an old Dell for deployment.
The platform requires an operating system to function, including hosting other OSes. It's free and open source, so it's accessible without cost. Whether it uses a command-line or graphical interface isn't specified—just refer to the "get started guide" for details.
Some users run virtual machines on Linux, while others switch to a Windows operating system.
If the system lacks an operating system, just set up Windows... if it runs Linux, you can definitely run a virtual machine, though game speed will be quite restricted. I believe you might not fully understand what a virtual machine is and how dual boot works. A VM functions like a software that mimics a processor, making the OS appear to run on a different machine. This lets you use another OS even when another is active. Because it relies on emulation, performance will be slightly reduced, but recent improvements have made the CPU impact minimal. For graphics, however, the drop is noticeable since the software can't use the GPU's special features. On compatible hardware, you can route a full graphics card through the VM, avoiding performance penalties, though this demands some technical expertise. Clearly, to run a Windows VM you must purchase the Windows version itself. Dual boot means placing both OSes in separate partitions (or HDDs) and letting the boot manager decide which to start, with manual control. They don’t run simultaneously; switching needs a complete restart. Because Linux uses a file system that Windows doesn’t understand, the latter won’t recognize the Linux drive (while Linux can access Windows partitions).
