Several boot methods for common Linux operating systems

Linux OS, is a computer operating system, the Linux operating system's kernel name is also "Linux." The Linux operating system is also the most famous example of http://www.aliyun.com/zixun/aggregation/29607.html "> free software and open source code development."

Simply put, Linux is a set of free and freely-propagated Unix-like operating systems that are primarily used on computers based on Intel x86 series CPUs. This system is designed and implemented by tens of thousands of programmers around the world. The aim is to establish UNIX-compatible products that are freely available to the world without the copyright of any commercial software.

The advent of Linux began as a computer amateur named Linus Torvalds, a student at the University of Helsinki in Finland. His aim was to design an operating system that would replace Minix (an operating-system-teaching program written by a computer professor named Andrew Tannebaum), which could be used on 386, 486, or Pentium processor PCs, and has all the functions of Unix operating system, so began the design of the prototype Linux.

Most Linux kernel-based operating systems use a large number of GNU software, including shell programs, tools, libraries, compilers, and tools, and many other programs, such as Emacs. That's why the GNU project's founder, Dr. Stallman Stallman, proposed renaming the Linux operating system as GNU. But some people only call the operating system "Linux".

The basic idea of Linux is two: First, everything is a file; second, every software has a certain purpose, and they are written as best as possible. The first, in detail, is that everything in the system comes down to a file, including commands, hardware and software devices, operating systems, processes, and so on, that are considered to have their own attributes or types of files for the operating system kernel. Linux is based on Unix, largely because the basic ideas of the two are very similar.

Let's talk about several common Linux operating system boot methods:

Method 1: Boot Floppy

(1) in Linux under the production of Mkbootdisk.

(2) If the hard drive leads to information loss, can not enter the Linux system to do boot floppy, for RH, with Redhat
Linux CD Boot into secure mode, when asked whether the hard drive of the Linux system set to the current environment, select "Yes", then the system into the hard disk of the Linux environment, run Mkbootdisk, do a startup disk.

(3) Take the same version of Linux boot floppy, modify syslinux.cfg file "Root=/dev/hdxx" for your Hdax, hdbx 、.... You can do it!
