Grub Customizer is a free utility that gives you an easily customizable user interface for managing GRUB entries. Using this utility, you can move, remove or rename the GRUB entries.
You can even edit the GRUB entries and the greatness of this utility is it keeps the entries updatable if you happen to do it using update-grub command-line.
Grub Customizer comes to your rescue when you want to reinstall the bootloader to the Master Boot Record (MBR). It supports GRUB2 and BURG.
Not just that, Grub Customizer can make your GRUB look good. You can change the background image and text colors.
Other features include setting a default operating system when you start the computer and also the ability to set the kernel parameters. Overall, I think this is a great utility for every Linux user in making GRUB clean and tidy, which otherwise used to be a tedious command-line process.
