GRUB2 Linux Boot Loader provides few customization options, that can transform it into an attention drawing eye candy. It’s main feature is the possibility to customize the splash screen being displayed with GRUB 2 menu entries upon system boot. This feature can be used not only in GRUB2 installed on hard disk for already installed operating systems, but also in GRUB2 Boot Loader placed on ISO image when booting from ISO/CD/DVD. This is pretty useful as well, when we want to create customized ISO image with the company logo based on some Linux Distro, which provides a company product.
In this tutorial we present how to create:
