Thank you very much for your feedbacks.

Does also not work: https://www.virtualbox.org/ticket/14062

I need to be a lil bit more precise: It starts, but it's so painfullly slow that windows (practically) not starts. And because of that slowness: No error messages - so no possibilities to debug??

.vhdx is not a supported format for VirtualBox vms. Change the option in disk2vhd to produce a .vhd image. You can then convert that to the native VirtualBox format .vdi . You may be offered the option to do that when you create the vm. I was last time I used disk2vhd to convert a physical machine to virtual .

Very slow operation suggests the Windows hypervisor is active. DO you see a green turtle with a V where you normally see just a white V on a blue background?

Picture website links between [img]'s has never worked, because [img] is only for pictures previously uploaded onto the forum servers, and available from your uploaded attachments found in your 'user control panel'. New pictures should be posted via Upload Attachment.

Regarding the slowness, if you don't see the green turtle as BillG notes, please upload a zipped vbox.log for that VM via Upload Attachment.

Thank you very much. Now i was successful. The slowness was due to the new "hardware" (virtualized) environment. It was necessary to re-configure some things...
