Can I boot windows 7 with an i3 9100?
I heard that intel's 9th gen processors only support Windows 10
And I wanna know if that's true
You can refer to the mobo product's website for Win7 support status.
Possibly but you should not use Windows 7 anymore. Windows 7 is not getting security updates anymore, it is open season for hackers. The only way it should be used is 100% offline.
