It will install now because it's still in Beta but once it's ready for full release it will not even install. The official full release of Win 11 will not install without a full UEFI capable Bios and TPM 2.0.
You can Sorta get the full retail version to work if you were to install a Beta and Upgrade to the full version but it will throw up a slew of TPM and Windows Hello errors every time you log on to your PC without hacking the shit out of your registry to disable it. Even if you can disable it, the Store App will be disabled and Windows Update may not work and certain drivers will fail to install.
I will be sticking with Win 10 until a proper workaround is ironed out or until Microsoft realizes how huge of a problem forcing everyone to install a $30-$50 TPM (Trusted Platform Module) on their motherboards or upgrade to a newer PC so that they can run Win 11.
