Today, I will talk to you about how to run Linux from CD. Many people may not know much about it. In order to let you know more, Xiaobian summarizes the following contents for you. I hope you can gain something according to this article.

A relatively new phenomenon in the Linux world is the emergence of bootable Linux CD distributions. It doesn't need to be installed to see what Linux systems look like.

Most modern PCs can boot from a CD, rather than having to boot from a standard hard drive. Based on this, some Linux distributions create bootable CDs containing Linux sample systems called Linux LiveCDs.

This sample is not a complete Linux system due to the size of a single CD, but surprisingly, you can add your own software. As a result, you can boot your PC from a CD and run Linux distributions without installing anything on your hard drive.

This is a great way to experience various Linux distributions without messing up your PC. Just insert the CD and boot! All Linux software will run directly from the CD. You can download various Linux LiveCDs from the Internet, burn them, and experience them. The following table lists some of the popular Linux LiveCDs available.

Knoppix is a Linux distribution from Germany and the first LiveCD Linux. PCLinuxOS A full-fledged Linux distribution in LiveCD form. Ubuntu is a world-class Linux project designed for multiple languages. Slax is a LiveCD Linux based on Slackware Linux. Puppy Linux A fully functional Linux designed for older PCs.

You can see familiar faces on this list. Many purpose-built Linux distributions have Linux LiveCD versions.

Some Linux LiveCD distributions, such as Ubuntu, allow the entire distribution to be installed directly from LiveCD. This allows you to boot from a CD, try out the Linux distribution first, and install it on your hard drive if you like. This feature is extremely easy to use.

Like all good things, Linux LiveCD has some drawbacks. Applications run slower because they have to access everything from CDs, and even slower when paired with older, slower PCs and optical drives. Also, since it is impossible to write data to CD, any changes made to the Linux system will be invalidated after reboot. However, there are some improvements to Linux LiveCD that help solve some of these problems. These improvements include:

Can copy Linux system files on CD to memory; can copy system files to hard disk;

Can store system settings on USB flash drive;

User settings can be stored on USB stick.

Some Linux LiveCDs, such as Puppy Linux, contain only a minimal number of Linux system files. LiveCD boot scripts copy them directly into memory when the CD boots. This allows the CD to be removed from the drive immediately after Linux boots. Not only does this speed up the program (because it runs faster from memory), but it also frees up the CD drive for you to transcribe audio CDs or play video DVDs with Puppy Linux's own software.

Other Linux LiveCDs also allow you to remove the CD from the drive after booting in a different way. This method is to copy the core Linux files as a single file onto the Windows hard drive. After the CD boots, the system looks for that file and reads system files from it. dyne:bolic Linux LiveCD uses this technique, which we call docking. Of course, you must copy system files to the hard drive before booting from the CD.

A very popular technique is to store Linux LiveCD session data on a common USB stick (also known as flash memory or flash drive). Almost every Linux LiveCD recognizes an inserted USB drive (even if it is formatted under Windows) and reads and writes files from it.

This allows you to launch a Linux LiveCD, create files using Linux apps, store them on a USB stick, and access them using Windows apps (or on another computer). How cool would that be?

After reading the above, do you have any idea how to run Linux from CD? If you still want to know more knowledge or related content, please pay attention to the industry information channel, thank you for your support.
