I’m trying to install Windows 11 on a brand new, today assembled computer. I just updated the bios on the Asus Prime B450-plus motherboard, which should support Windows 11.
The installation program starts ok from a usb stick but after entering the product key it just says that this computer doesn’t support Windows 11.
I’ve checked that AMD fTPM switch is enabled and that secure boot setting is Other OS.
How can I find out what’s causing this?
