Problem with Batocera installed on extern USB -> vhdx not boot with ventoy

[FireBirds]

Hello.

My English is not so good, better is german.


I have the Batocera 37 Image with Etcher on extern USB (NVme SSD) 500GB installed and everything set up and configured.

After I've finished setting up Batocera. Do I have this USB to an image As a test, already created a vhdx, vhd, vdi and then booted into Ventoy.
Unfortunately it does not work with ventoy.
Then only screen /Windows/System32/Winload.efi" not found.
Batocera loads from Syslinux or?

Does anyone have any ideas that it boots at Ventoy.
The external NVme SSD with Batocera boots perfectly. Only in ventoy the images vhd, vhdx, vdi is not

Thanks
