Installing Windows 2000 on a 2006 Mac mini is technically possible but pretty impractical. The hardware in that era Mac mini uses EFI firmware and drivers that were never designed for Windows 2000, so you’d run into driver gaps for things like graphics, networking, and even disk controllers. You could try using Boot Camp or a virtualization layer, but Boot Camp didn’t officially support Windows 2000, so you’d be hacking around unsupported territory. Virtualization is usually the safer bet, since it abstracts away the hardware and gives you a more stable environment.
Even if you managed a bare‑metal install, you’d likely face instability and missing functionality, so it’s not something I’d recommend for production use. If your goal is just to run legacy apps, virtualization is the way to go.
So you can force it, but it’s messy and not worth the pain compared to running Windows 2000 in a VM.
