I tried to help my brother, who is a computer scientist to install windows 11 on his new am5 motherboard build. Am5 was really new and even with our combined knowledge it took all day of fucking with it to find a way to get windows 11 to recognize the m2 ssd. We had to load it with an older driver from the manufactures website and we had to do some kind of shenanigans to get the installer to actually recognize the files. Iirc this was a gigabyte motherboard, a reputable brand.
This was when am5 was newer so it’s kind of understandable I guess, but I also installed arch for troubleshooting purposes that day and it only took 30 minutes 🤷
