If you are planning to roll out numerous Ubuntu-based servers, you can download the default ISO, install the operating system on each machine, and then install the necessary software. But what if each of those servers will need the same list of software packages installed? Why go through the hassle of manually adding those packages after you've installed the OS? If there were a way you could create a custom Ubuntu ISO, which includes all the necessary software, wouldn't that be the most efficient means of handling this task?

Want to download via-bitTorrent links, get DVD images with more language packs, use the text-based alternate installer or find previous versions of Ubuntu? Download the latest LTS version of Ubuntu, for desktop PCs and laptops. LTS stands for long-term support — which means five years, until April 2023, of free security and maintenance updates, guaranteed. Oct 4, 2017 - Afterwards, an Ubuntu ISO image must be downloaded. The ISO is now automatically applied to the flash drive, this can take a few minutes. As soon as the boot menu appears, select your stick and the installation will start. I am using Ubuntu in the example, and you can download ISO images for Ubuntu from the link below: Download Ubuntu Linux. Step 3: Install Linux using VirtualBox. It should take 10-15 minutes to complete the installation. Once the installation finishes, restart the system.
Good thing such a tool exists.

Cubic is a custom Ubuntu ISO creator. With it you can take a standard Ubuntu ISO image, install all the third-party software you need, and then create a custom, bootable (and installable) image from that. In the end, you'll have a Ubuntu platform that includes all the software you need, without having to add everything post-install.
I'm going to walk you through the process of installing and using Cubic. Once you know this tool, you won't want to work without it.

Installation
I'll be installing on Elementary OS, but the tool will install on any modern Debian-based distribution (so long as said platform has a GUI desktop). Open a terminal window and issue the following commands to install Cubic:
That's all there is to the installation. You should find an entry for Cubic in your desktop menu. Click to start it and you'll be prompted for your sudo password.
Usage
The first screen requires you select a project directory (Figure A). You can have only one project per directory, so make sure you are using a new directory for each custom ISO (or delete all project files when the task is complete).
Figure A
In the next window, you must select the original ISO image to be used for the creation of the custom image (Figure B). I'm going to use Ubuntu 16.04 and add Kubernetes to that image. Once you select the image, the rest of the information will automatically fill in. Do not change anything in the Original ISO section. You can, however, change information in the Custom ISO section.
Figure B
Click Next and you will eventually find yourself in a terminal window indicating you are in a chroot environment (Figure C).

From this terminal window, install all the applications you need in the standard fashion (via apt or apt-get). Once you've completed this task, click Next. You will then see the kernel image being used for the ISO. You can't change this, so click Next again. At this point Cubic will begin building your custom ISO (Figure D). When it completes, click the Finish and your new disk image is ready and can be found in your project directory.

The final screen does allow you to delete all project files (minus the generated disk image). Unless you have a need for the files, I'd recommend you do this. Burn your ISO image onto a CD/DVD or USB drive (or use it for a VirtualBox VM) and you're ready to install your custom platform.

Easy does it
That's all there is to creating a custom, installable ISO image based on an original Ubuntu disk image. If you're looking at deploying numerous Linux servers (each of which will be based on the same collection of software), I highly recommend you giving Cubic a try. This easy-to-use software will save you time, especially when rolling out a data center filled with Ubuntu servers.

A bootable USB drive is the best way to install or try Linux. But most Linux distributions—like Ubuntu—only offer an ISO disc image file for download. You’ll need a third-party tool to turn that ISO file into a bootable USB drive.
You’ll need to download an ISO file to do this—we’re going to use Ubuntu in our example, but this should work for quite a few different Linux distributions. Head to Ubuntu’s download page and download the version of Ubuntu you want—either the stable “Long Term Service” release or the current release. If you’re not sure which one to download, we recommend the LTS release.
Below, we’ll show you how to turn this ISO into a bootable flash drive on both Windows or an existing Linux system.

NOTE: This process creates a traditional live USB drive. When you run it, none of your chances (like installed programs or created files) will be saved for the next time you run it. For installing Linux to your PC, this is fine—but if you want a live USB that keeps your changes so you can use it regularly on different computers, you’ll want to check out these instructions instead.
How to Create a Bootable USB Drive on Windows
There are many tools that can do this job for you, but we recommend a free program called Rufus—it’s faster and more reliable than many of the other tools you’ll see recommended, including UNetbootin.
Download Rufus and run it on your Windows PC. The tool will open immediately—you don’t even have to install it.
Connect a USB drive with at least 2GB of free space to your Windows PC (this may vary depending on your distribution of choice). The contents of this drive will be erased, so back up any important files on the drive first. Click the “Device” box in Rufus and ensure your connected drive is selected.

Activate the “Create a bootable disk using” checkbox, click the button to the right of it, and select your downloaded ISO file.
Once you’ve selected the correct options, click the “Start” button to begin creating the bootable drive.
You may be told you need newer SysLinux files. Just click the “Yes” button and Rufus will automatically download them for you.
Rufus will ask how you want to write the image. Just select the default option—“Write in ISO Image Mode (Recommended)”—and click “OK”.
You’ll be warned that all data on the USB drive will be erased. Click “OK” to continue if the drive has no important data on it. (If you forgot to back up your data, click “Cancel”, back up the data on the USB drive, and then run Rufus again.)

Rufus will create the bootable USB drive. You can click “Close” to close Rufus when it’s done.
Next, restart your computer and boot from the USB drive using these instructions. You can also take it to another computer and boot Ubuntu from the USB drive on that computer.
How to Create a Bootable USB Drive on Ubuntu
If you’re already using Ubuntu, you don’t need to do this from Windows. Just open the Dash and search for the “Startup Disk Creator” application, which is included with Ubuntu.

Provide a downloaded Ubuntu ISO file, connect a USB drive, and the tool will create a bootable Ubuntu USB drive for you.
Many other distributions have their own similar tools built-in, so you’ll have to check and see what your particular distribution has available.
