What is the Grub Bootloader?

Grub stands for \"Grand Unified Bootloader.\" It is an open-source bootloader designed for Unix-like operating systems, including Linux.

Using Grub, you can choose which operating system you want to boot, making it easy to switch between different operating systems.

While Grub is the most popular bootloader for Linux, it is not the only one. Some alternative bootloaders include LILO (Linux Loader), SYSLINUX, and rEFInd. Each of these bootloaders has its strengths and weaknesses, and which one you choose will depend on your needs and preferences.
