First steps under Linux territories. Learn how to install and use Ubuntu Operative System.
By the way, this is just a 101 tutorial. Later we’ll post more interesting stuff. 😉
0.0 – REQUIREMENTS
When choosing a PC to host Ubuntu you need to guarantee that you have enough disk space and that it complies with the following recommended system requirements:
- 2Ghz dual core processor or better
- 2Gb system memory
- 25Gb of free hard drive space
- internet connection
If you want everything running perfectly smooth, hardware compatibility is a must. So, for a full specs laptop, we recommend you to buy it from System76. An American based company that builds custom made native linux pcs.
1.0 – DOWNLOADING THE ISO
Well, buying the computer is the easiest part. Now let’s get to action!
For downloading the Ubuntu ISO go to www.ubuntu.com and click on Downloads>Desktop.
The Ubuntu webpage will present you with two main alternatives, the Long Term Support version, commonly know as “LTS” and the latest version for cutting-edge updates.
We recommend you to choose the LTS version as it has long term support from Canonical, which means more stablility.
2.0 – CREATING A LIVE USB DRIVE
Now that you’ve selected your machine and downloaded the ISO file you need to find a clean USB Drive to flash it with a working copy of Ubuntu.
Your flash drive needs to have at least 2Gb of space. We recommend 16Gb for running Ubuntu from it…..and YES, you can run Ubuntu from a flash drive! But that’s another story.
There are many tools online for creating bootable USB flash drives. The one we recommend is Rufus. A lightweight portable software.
So, go to a windows computer download this software and run it.
Once the software kicks it SHOULD automatically detect your USB drive. In all cases PLEASE TRIPLE CHECK THAT THE DEVICE NAME MATCHES THE USB DRIVE YOU WANT TO FLASH!!!
Then, add the Ubuntu ISO file by pressing the “CD Rom” icon.
Double check, again, the devide name and press “Start” to begin flashing.
Then confirm the recommendation “write in ISO image mode” by pressing “OK”.
And that’s it. You are now a respectful owner of an Ubuntu Live USB flash.
Please eject the pen drive safely and proceed to the next chapter.
3.0 – MAKING SPACE FOR UBUNTU
When you buy a computer with a pre-installed version of Windows, the OS tipically ocuppies the whole space of the disk. But most of that space is still empty, so you need to resize the main windows partition, tipically called C:\, to get some free space to add Ubuntu’s partitions.
And now you may ask “what are partitions”?
“Disk partitioning or disk slicing is the creation of one or more regions on a hard disk or other secondary storage, so that an operating system can manage information in each region separately. Partitioning is typically the first step of preparing a newly manufactured disk, before any files or directories have been created.”
Disk partitioning. In Wikipedia, The Free Encyclopedia. Retrieved 22:35, December 13, 2016.
As a conclusion, partioning is the act of splitting a hard drive in smaller sectios, creating new virtual “hard drives” to accomodate new OS’s. That’s how Windows and Ubuntu, for example, can share the same physical space without smothering each other.
So now that you should know what a partition is, it’s time to shrink Windows down.
Press the Start icon and type
disk management. Windows will prompt you with a fancy name like “Create and format hard disk partitions”. Click on that.
The Disk Management will pop up and show you the actual partitions you have on your hard drive.
Right-click over your Windows partition, commonly designated by C:/, and select
If you’re not sure of which partition to shrink, take a look at your file explorer under Local Disk. There you’ll find the Drive name under parentesis (X:/).
On the Shrink window you’ll see the Enter The Amount of Space To Shrink In MB. This parameter lists the total amount of space that will be removed from the volume.
Beware that the initial value highlighted in blue defaults to the maximum amount of space that can be removed from the volume. So if you want you can leave that value unchanged. On the other way, if you have 500Gb or more space available on your Hard Drive, be generous. Leave, for example, 70% of the total Hard Drive for Windows and give the remaining free space for Ubuntu.
Congratulations! You have just created additional space for your Ubuntu.
4.0 – INSTALLING UBUNTU
Now shut down your computer. Plug in your newly created bootable flash drive in one of the USB slots of your pc. Turn it back on and start pressing the BIOS shortcut key* right from the beginning.
*F12 or Esc keys usually works, but it depends on the manufacturer. So for confirming which key activates the BIOS of you pc please take a look at the following site or refer to the manufacturer’s manual.
Your BIOS should start. If it doesn’t start, please shut down the computer and try again.
Now go to the Boot Options and prioritize the external devices over the rest of the options, so that your computer can boot from a bootable flash drive.
Save the changes and exit. Your pc should now restart and boot from the flash drive.
A welcome screen should now appear with two options: Try Ubuntu and Install Ubuntu.
Let’s go for the install option.
Now authorize the installer to Download updates and third-party softwares by checking both boxes.
On the installation type, we are going to select “Install Ubuntu Alongside Windows X“.
Press Continue again and follow the rest of the installation setup. Ubuntu should install successfully on your computer.
