used to work on 5mb hard drives in the late 70's. they where the size of fridges.
but I digress to create a menu right click any menu and select customise
you should then a dialog with 3 tabs, toolbars, commands and options.
select toolbars and click new select the properties and set the tool bar to a menu.
if you require drop down menus then select new menu from the command tab.
Select the command tab and drag what you want onto the new menu bar.
when completed set this menu in the startup parameters.
