Boot loaders such as GRUB (Grand Unified Bootloader), LILO (Linux Loader) etc. enable you to select to boot a particular operating system in multiboot or dual boot systems. After selecting the operating system (for example Linux), the booting process initially starts with the booting of Linux Kernel program. A Linux Kernel program is the central component of a computer operating system. It requires the corresponding drivers to access the device on which the file system is based. To avoid any conflict due to all imaginable drivers in the kernel, it uses initial ramdisk (intrd). The intrd is the temporary file system, which is mostly used for preparations before the real root file system can be mounted. Problems might occur when intrd gets loaded before Linux Kernel program. In such situations, the hard drive volume becomes un-mountable and the data saved in the hard drive becomes inaccessible. In such situations, you need to recover your data from the latest backup. In case, no backup is available or the backup is corrupted, you need to use efficient Linux Data Recovery applications to recover your lost data files.

Consider a practical example, when you attempt to boot Linux operating system, you encounter the below error message:

“Must load Linux kernel before initrd”

The above error message occurs each time you try to boot the Linux operating system on your computer. After the above error message appears, the data saved in the Linux volume becomes inaccessible.

Cause:

The above error message mainly occurs when the intrd gets loaded before the Linux Kernel program.

Resolution:

To resolve the above error and access the data, you need to remove the intrd from your computer. However, if you still encounter an error, then only option left is to access the volume by reinstalling the Linux operating system. A clean reinstall of the operating system will erase all previously stored data in the hard drive. In such scenarios, you need to recover lost data by using effective Linux Data Recovery software. These advanced recovery applications incorporate high-end scanning methods to recover lost data from a logically corrupted hard drive.

Stellar Phoenix Linux Data Recovery serves the purpose of providing reliable and easy Linux Data Recovery. This read only Linux Recovery software supports Ext2, Ext3 and ReiserFS file systems. It gets installed on Windows (Vista, XP, 2003 and 2000) and the affected Linux drive should be connected as slave.

What is Linux?

Linux is an operating system created by Linus Torvalds during his days as a student at the University of Helsinki. Linux was created and meant to be used as an option or substitute to the other operating systems being used by computer users, like MS-DOS, Windows, Mac OSX, etc. Linux is not a program or a set of programs like a word processor of an office suite.

A Brief History

While studying at the University of Helsinki, Linus used a version of the UNIX operating system called ‘Minix’. Several requests for modifications and improvements for the operating system were being sent by Linus and other users to Andrew Tanenbaum, Minix’s creator, but he felt that they weren’t necessary. Therefore, Linus decided to create his own operating system; one that would take into account the users’ comments and suggestions for improvements.

A “kernel” is the focal point of any operating system. Without going into great detail, the kernel tells the CPU to do what you want the program or application that you’re using to do. An operating system would not exist without a kernel. However, a kernel is also useless without any programs or applications.

In 1991, two critical situations evolved that would serve as the starting point for Linux. A kernel was already created by Linus, but he had no programs to use; some programs were available from GNU and Richard Stallman, but they had no working kernel. So Linux was born by combining the programs from Richard and GNU in Cambridge, Massachusetts, with the kernel provided by Linus in Helsinki, Finland. It was a lot of ground to cover and far to travel, so the Internet became the primary method of getting Linus’ kernel together with the GNU programs. It can almost be said that Linux is an operating system that came to life on the Internet.

Not For Everybody at First

Other software companies will sell you software contained in a CD or a set of floppies, together with a brief instruction booklet, and in half an hour or probably even less, you could install a fully functional operating system on your computer. You only needed to know how to read and follow instructions in order to install it. This was what those companies had in mind when they developed their operating systems. However, when Linux was developed by Linus, this factor wasn’t initially considered. Later on, Red Hat and other likeminded companies made it their purpose to develop Linux to the point where it could be easily installed just like any other operating system in the market, by anyone who can follow simple instructions, and today we can definitely say that they have succeeded in this particular purpose.

Linux Today

Nowadays, there is a great deal of favorable reactions from computer users regarding Linux. The fact that Linux has proven to be impressively stable and versatile, especially as a network server, surely has played a big part in this popularity. Down-time is minor or insignificant when Linux is installed and used as a web server or in corporate networks. Many cases have been reported wherein Linux-powered servers have been functioning smoothly for even more than a year without needing to re-boot, and when it had to be taken down, it was only for a brief period for maintenance purposes. Its cost effectiveness has become to be one of its strongest selling points. Linux can be installed and run on either a home PC or a network server, without having to spend as much as it would be for other software packages. More reliability and less cost – it’s ideal.

“Linux Distribution” or call briefly that is “Linux Distro” which born from the requirement Distribute Linux Operating System go to the favor extensively. The “Distribution” word is the extensively meaning there is appear in every the society, there is person group want to announce the idea of oneself goes out to others.

For linux distro that is person group they want to announce linux operating system to others turn to take an interest and lead the linux operating system to be usable more and more extensively there. The power adds that make up the linux distro that have as follows.

First, because of in the age at linux start the internet system still have a few speed extremely then not convenient to download linux kernel and all linux components come to set up because more will fully completed download it get time long ago. So, CD-ROM saller group for sets up a linux program then important duty first of linux distribution.

The second points, is in the age at this first also at all program at the components of linux operating system still during of development goes to according to one’s ability of program developer from the worldwide, thus leading linux to usable have rather a little moderately, So mostly software that distribute then is in “source code” which the lead will go to usable must use the technical step that calls “Program Compilation” then make not convenient or almost impossible to build the favor happen in group of newcomer users quickly follows the aim of linux distribution. So the linux distro group must prepare operating system software of oneself are in fully use actually then get achieve.

The third points, that is the hard step for linux operating system installation must touch redesign for easyly most don’t differ from order calling setup command in windows installation, including setting all the usability and refining the system for just boot with Linux CD-ROM and click next go to continually already you will have linux operating system that want, simple that is linux distro must making usability linux get into simple for general person.
So, linux distribution then group of person are the organization there is the objective to announce the operating system that uses linux for kernel to general person to extensively usability by operate beneath the regulation of the OpenSource community and FREE Software which in now have linux distribution increase greatly.

This is the basic about the origin of linux operating system and linux distro distributing to other linux users. Linux learning is easiest in now vendor of each linux distro they has created it for easy to use and easy fast install, So you can learn on same the windows os.
