To change the boot background using grub for Linux
Concept
Linux, whose full name is GNU/Linux, is a set of Unix-like operating system that is free to use and spread freely. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and Unix. With the development of the Internet, Linux has received support from software enthusiasts, organizations and companies all over the world. In addition to maintaining a strong momentum of development in servers, it has made great progress in personal computers and embedded systems. Users can not only intuitively obtain the implementation mechanism of the operating system, but also modify and improve Linux according to their own needs to maximize meet the needs of users.
GNU GRUB (GRand Unified Bootloader referred to as "GRUB") is a multi-operating system startup program from the GNU project. GRUB is an implementation of the multi-boot specification, which allows users to have multiple operating systems in the computer at the same time and choose which operating system they want to run when the computer starts. GRUB can be used to select different kernels on operating system partitions or to pass boot parameters to those kernels.
