thankyou for replies,
i dont ask to add kernel modules as longpanda suggested.
as i write in my first post version 8.x and 9.x worked perfectly booting from ventoy using .img files.
i simply was asking what are differences in 10.x that prevents booting in the same manner.
im not expert enough to try to add kernel modules.
in every case thankyou very much for replies and i apologize if i have done something of wrong
