Add or Modify a Boot Menu Entry

With a Bios system

You can add an entry or modify the one you select first, by pressing the relevant button in the Bootloader Configuration screen and editing the screen that pops up on top of it.

If you have chosen Grub 2 as your bootloader, you cannot use this tool to edit entries at this step, press 'Next'. You need to manually edit /boot/grub2/custom.cfg or use grub-customizer instead.

Some things that can be done without any risk, are changing the label of an entry and ticking the box to make an entry the default one.

You can add the proper version number of an entry, or rename it completely.

The default entry is the one the systems boots into if you don't make a choice while booting up.

Editing other things can leave you with an unbootable system. Please don't just try something without knowing what you are doing.

With an UEFI system

In this case you are using Grub2-efi and you cannot use this tool to edit entries at this step. To do that you need to manually edit /boot/grub2/custom.cfg or use grub-customizer instead. All you can do here, is to choose the default entry in the drop down list.

After a click on the Next button, another drop down list allows to choose the video resolution for Grub2 which is a graphical boot loader.
