A rquest to dev of this great Tool WinNtSetup have been using it since a long time . i tried to create Win10 VHD EFI Based to be used via Ventoy boot USB but when i tried to boot it results into error . Please if somebody have any time to test so that dev will look into it & will resolve it asap in next release.
but
if we create win 7 or 10 VHD or VDI via virtualbox then it works flawlessly with Ventoy.
