Hah I literally did the exact same thing. When I bought my current laptop it came with Windows 11. When I powered it on while I was looking for my USB stick it started loading Windows, I restarted into the USB and installed my Linux distro. I mean, literally I have no use whatsoever for Windows even for a moment.
I wanted to go with raw Debian but at the time the audio device was very new on the market I think, or whatever the reason, I had to put Kubuntu which had all the necessary drivers to fully support all the hardware on the system. I'm very happy with it. It's a kick ass laptop. Why would I want to infect a superb computer with Windows!
Is there not already ReactOS? Or has that been abandoned?
