I want to change my default boot OS in GRUB2. But the only way I know of seeing the order of the OS I want in the GRUB menu is doing a reboot and seeing the menu displayed.
grub.cfg there are many more
menuentry lines than actual choices in the GRUB menu, so I can't identify in that file the one I want.
Is there any place where the actually displayed menu is stored so that I can see it without having to reboot?
