第 9 章 GRUB 引​​​​​​​导​​​​​​​装​​​​​​​载​​​​​​​程​​​​​​​序​​​​​​​

When a computer with Red Hat Enterprise Linux is turned on, the operating system is loaded into memory by a special program called a boot loader. A boot loader usually exists on the system's primary hard drive (or other media device) and has the sole responsibility of loading the Linux kernel with its required files or (in some cases) other operating systems into memory.
