A CD or DVD with Linux on it is a useful thing to have! There are quite a few things you can do with it:
- You can try Linux out without installing it. Just putting the CD in the optical drive and running Linux from there won’t touch your main operating system or files. Using it like this can actually help you fix a Windows computer–you can still access the hard drive and back up all the files that are on it from Linux even if Windows is acting weird. (You can also use it to kind of crack into your machine if you’ve been locked out for some reason, but don’t try it on a network because the sysadmin will notice and flip out. You didn’t hear this from me.)
- You can install Linux alongside or instead of your main OS–be careful about your files if you’re doing a wipe-and-install, of course, and be careful about partitioning your drive too. Make sure you have a backup of at least everything important if you do it this way!
- You can also install Linux on a virtual machine, although using the .iso file you download from the Internet and burn to the CD works just as well for this.
So how do you make one? It’s pretty easy:
Get yourself a blank CD or DVD.
Some distros won’t fit on a CD and you’ll have to use a DVD. If you don’t know what this means yet, get a DVD.
Pick a Linux distribution (or “distro”).
There are lots of different “flavors” of Linux. They might look a little different, or be designed for special systems or specific groups of users.
If you’re new to all this, I suggest Mint or Xubuntu. They look a lot like Windows, so they’ll seem familiar, but they’re way better! And they’re a breeze to install. Normal Ubuntu I wouldn’t recommend as a first distro, actually; the user interface it comes with is kind of clunky. The only difference Xubuntu has is that it looks simpler and that makes it a little easier to use.
If you’re curious or you’ve tried this before, try searching around for a distro that’s particularly suited to you. I’m quite fond of Debian, but I’ve been playing with Elementary, which looks more like Mac OS X than the normal Windowsy-looking interfaces.
Mint and Xubuntu are great general-purpose distros. Xubuntu is probably the better one on older computers–I’ve made a ten-year-old box on two gigs of RAM run like a decent computer by installing Xubuntu. If your computer is THAT old, you’ll want 32-bit; otherwise, use 64-bit.
A word about some terms you’ll see. Unless you’re developing or testing for the distro as a project–in other words, if you’re a normal user–you won’t want to use the development versions. Anything that says “nightly release” or whatever, stay away from using as a main operating system because it’s still in testing.
“LTS” means “long term stable.” That is a GOOD thing to download. It may not be the very most recent version, but it’s a well-tested one that’s going to be supported for a reasonably long time.
You can also just get the most recent stable release. Those or LTS releases will be fine.
Download the .iso file
Either from the Internet directly or as a torrent. Googling the name of your distro should make it pop up. Where possible, always use a download link suggested on the project web site. There are probably multiple “mirrors” to download from; try to choose one that is on the same continent as you.
Any computer with 4 gigs of RAM or more should be using 64-bit operating systems. That’s probably what you want unless your computer is really old.
A torrent is a more reliable way of getting a distro if you have a torrent client set up. They’ll keep going even if they’re interrupted, and they’re less expensive for the maintainers. However, the clients are kind of tricky to set up, at least in my experience. There’s nothing wrong or sketchy about torrenting Linux distros–you can use torrent clients to get hold of sketchy Internet stuff, but that’s not what we’re doing here, this is super innocent and it’s just another way to get your .iso file.
Burn the .iso file to the CD
You probably know how to do this on your computer. If not, Google it. It’s pretty simple.
Label the CD, and maybe put it in a paper sleeve
Lots of people forget to do this, and it’s really confusing! Make sure you mark your CD with the distro name (e.g. Linux Mint), the version number (e.g. 18), and whether it’s 32- or 64-bit (probably 64).
Optional but fun: Burn more CDs for your friends
“Did you get it to do that thing you were trying?”
“I figured out how to install programs!”
“I found a tutorial about the command line!”
“My resolution is acting funny, anyone have ideas about that?”
This is why Linux User Groups exist. Get enough nerds in one room playing with a shiny toy and something fun is going to happen.
