Issues with windows vista/7 ISO's with ventoy

Vista is not in the list

A no valid partition error might be because your disk was previously a GPT disk. You may need to use diskpart to clean it and convert mbr

win 7 may not contain USB drivers. You may need to find an ISO with added USB drivers.

I did double check if the USB disk is GPT, and it wasn't. I have already wiped it by "clean" command in diskpart.

As for the vista being unsupported, I just wanted to check if it's really not going to work. Let's focus on the w7 ISO now.

Any ideas?
