Hi mrabdalkadr
or i guess it would be much simpler to change that timeout in the 'create iso' plugin in the 'Finals' section. It's in the Multiboot options
on the right hand side and then hit the Create new ISO button or pref. build it that way in the first place
on a prebuilt one you could also edit the menu.1st file in the ISO\TI folder and then rebuild the iso from FINALS-Create ISO plugin
