Hi guys,
sorry for my English :D. I was able to come up with some workaround.
once you land in the Shell>
1.fs0:
2.edit startup.nsh
3. now in the editor enter the location of the BOOTx64.EFI “\EFI\BOOT\BOOTx64.efi”
4.still in editor left ctrl+s = save and hit Enter to save
5. left crtl+q = quit
you can now reboot the machine, it still lands in the shell but after a 1s it starts loading.
Hope this helps for now.
Peter
