The VM was win 10 upgraded to win 11 which is why the GA was not updated plus stuff worked fine on my X99 i7 5930K so I didn't see the need to update the GA. This will boot your Windows 11 Enterprise system. 3: Install the Guest Additions You should consider installing. Go to the System settings found on the left-side panel and uncheck the box beside Enable EFI (special OSes only). Your host machine should have at least 1 GB of RAM and plenty of CPUs remaining so the host OS and VirtualBox can function smoothly.

But why do you use the very outdated VirtualBox Guest Additions (GA) 6.0.8 inside the guest? You're using a Windows 11 host and guest, a '12th Gen Intel(R) Core(TM) i9-12900K' CPU with 16 cores and 24 threads, and VirtualBox 6.1.29r148314 (running in NEM mode).
