In this article I show the manual Windows 11 installation and the first insights. The version used is from the Beta Channel, the Windows 11 Enterprise 21H2 (OS Build 22000.194) version. Since Windows 11 is already installed on my test hardware via in-place upgrade, I use a Hyper-V VM for this. It is absolutely necessary to use a VM of the 2nd generation. SecureBoot and the TPM must also be activated in the VM, otherwise the installation will fail.
