Ventoy USB pendrive is not listed in boot devices

[Epictetus77]

Hi guys.
My USB pen drive where is Ventoy with .iso images of operating system is lot listed in USB boot devices, at all.
So when I go to laptop boot options/menu, USB device should be there but it is not.
I tried on multiple laptops, nope, laptop does not see USB pen drive and Ventoy.
I googled this issue, advice was to disable secure boot, but this moring I pluged the USB pendrive on my HP ZBook 17 old laptop, and again same issue, USB pendrive is not seen in boot options.
I think even this laptop does not have secure boot option, have not seen it in BIOS.
I don't have issue with normal USB pendrive devices.
What have I done wrong during procedure of making Ventoy USB pen drive?

Try another pendrive. If the result is the same, then I dont know, but if the other pendrive works it might be that the first pendrive has a problem
