Problem booting Windows Server/Client ISOs with UEFi in VB 6.0.6

[mknuel]

I have a general problem to boot actual Windows Server/Clients ISOs with UEFI under VB 6.0.6
It starts to boot from the ISOs with "Loading Files..." correctly but after that it stucks with the VirtualBox Logo forever.
Tried also to change the Settings a little bit but nothing helps... it worked as i can remember under VB 6.0.4

Thanks for help!

Please zip the log file and attach it to the thread. Most people won't go looking at third party sites. Plus, if the third party site ever disappears or deletes the file the context to the thread is lost.

It appears that you have Hyper-V enabled on your host system (or something else enabled that is making use of it). This means that you are not using the native virtualisation support in VirtualBox but it is attempting to use Hyper-V instead. You probably see a green turtle icon on the bottom right corner of the guest window. The icon is used because this new feature in VirtualBox 6.0.x is glacially slow.

Follow the instructions in FAQ: I have a 64bit host, but can't install 64bit guests to try to disable Hyper-V. Bear in mind with later versions of Windows you also need to disable "Containers", "DeviceGuard", "CredentialGuard".
