Install Grub Customizer, a Graphical Grub Boot Manager Editor. Much easier than editing Grub by hand. Why risk a manual edit and fat-fingering something then ending up and a non-working copy of Grub? To me, it's not worth the risk. This program worked well for me on both MBR and UEFI/GPT hard disks. You can easily install it in a terminal session. From the Linux desktop press Ctrl+Alt+T on your keyboard to open the terminal session. When it opens, paste these commands below one by one and press Enter after pasting or typing each command: sudo add-apt-repository ppaanielrichter2007/grub-customizer sudo apt-get update sudo apt-get install grub-customizer Now if you check in Menu, Applications. Grub Customizer should be there. Start it up and make any desired changes in boot listings, boot order, even color of menu, and a background picture, etc. After making all of the desired changes to Grub, make sure to select: File, Install to MBR
I saw, somewhere on the net, a boot menu with options to choose from different OS'es that looked like a graphical interface. Is it possible that this Grub Customizer to be that 'thing' I saw? I wanted the boot menu to be like that (graphical interface) but didn't know where to look or how to install.
Yup, the link in my previous post has step-by-step instructions... Sorry, didn't realize there was a June update - that's good news.
