I'm trying to customize the Grub 2 menu. I have Win 10, Ubuntu, Win 7, Win 95, Win XP on my hard drive.
The Grub Bootloader can see Win 10, Win 7, and Ubuntu. It does not see the other 2 operating systems.
I can create a sub-menu addition(named Other Windows Systems) but do not know how to direct Grub to the particular partitions.
I searched for command lines but being new to Ubuntu I don't understand what I need to do.
Thanks for the help. I am on the road and will try your suggestions when I return.
