Quote:the only "change" that i did is to put ventoy.dat file to all the isos with ultraiso to make them compatible
According to https://www.ventoy.net/en/compatible.html Windows ISOs are not Ventoy Compatible so why do you think you need to add a ventoy.dat file?
What about an unmodified ISO file? There is no need to modify ANY ISO file, Ventoy 'just works' with 99% of all unmodified bootable ISOs.
