creating a usb stick with mp4 files and a menu to navigate between those files

Hey Balena,

I am a hobbyist musician. I was used to make DVD’s with my songs and short video’s attached on these songs. This to share my music with my environment.
today I need to create the same menu and video songs but than on a USB stick because DVD’s are outdated.
That is why I did create an iso file with my mp4 songs and also a menu to start with.
this I did accomplished with a program called DVDfab 13.

But when using Balena Etcher to burn the iso file on the stick I receive an error massage.
namely: Missing partition table!.

Please can someone help me out of this situation.
What do I have to do to succeed?

Best regards,

Stefaan De Reu
