Ubuntu updating bootloader
GNU GRUB has been the number one choice among the available system bootloaders for many years now, so replacing such a trusty piece of software for something else isn’t exactly common among Linux users.That is why I will suggest to replace it with a fork of GRUB that is called BURG.
sudo add-apt-repository ppa:danielrichter2007/grub-customizersudo apt-get updatesudo apt-get install grub-customizer Upon launching the app, it should automatically detect BURG and offer you the option to configure this one instead.
Elementary OS Loki and above users need to first enable PPA before proceeding further. STEP 2: Copy and paste the following in the Terminal and hit enter.
This command will add the Boot Repair’s PPA repository sources to your PC.
Before you rush on restarting though, enter the command “sudo burg-emu” that will let you emulate a boot screen and configure the loader as you please.
As you can see, BURG offers the three latest kernel versions for the detected operating system, as well as “shutdown” and “restart” options.
