How To Install elementary OS 0.4 Loki


 A Brief About Elementary OS

 elementary OS is a Linux distribution based on Ubuntu. It is the flagship distribution to showcase the Pantheon desktop environment,[3] similar to how Linux Mint introduced Cinnamon.

This OS is only supported on 64bit machine.  Before you think of installing it, make sure that you check the architecture of your computer.

  •  In windows machine, right click on my computer, go to propertise and check the system type. it should read as 64 bit operating system
  • In linux machine, run the command lscpu from your terminal. The output of this command will be somewhat as below

      How to Install Elementary OS 0.4 Loki

This tutorial explains how to install the newly released elementary OS Loki step by step. It assumes every reader is new to GNU/Linux, especially to elementary OS. You will install Loki by at least 12 steps at total time needed around 40 minutes. We hope you love elementary OS and use it happily.


Recommended Requirements

  From elementary OS official documentation, it requires these specification:
  • Intel i3 or comparable dual-core 64-bit processor*
  • 1 GB of system memory (RAM)
  • 15 GB of disk space
  • Internet access
*) You can only install elementary OS Loki in 64 bit computers. A 32 bit computer can not run it. To check whether your computer is 64 or 32 bit, check this article as example.

Preparation


We assume you have downloaded the elementary OS Loki iso file. Then burn the iso file to a USB flash drive to make it a bootable disk. You may use Unetbootin (GNU/Linux and Mac) or Rufus (Windows) program to do it.

Prepare your hard disk drive first to have these items:
  1. A blank partition sized at least 20 GB. This will be the main partition (where Loki lives). 
  2. A blank partition sized at leas 2 GB. This will be the swap. 
  3. You can create them easily with GParted program.

Boot Up


Insert your USB drive > restart your computer > enter BIOS > set first booting into USB > restart > if you see any selection, select elementary OS (default) > if you should choose between Try and Install, select Try > you enter the desktop > open desktop menu (at top-left corner) > click Install elementary OS > an installer window comes. This window is an operating system installer called Ubiquity.


1. Select Language


The first page of Ubiquity (the elementary OS installer) will ask you for your prefered language. Choose English, or, at your option, your mother language.




2. Select Network Connection


Second page of Ubiquity asks you about whether to use a network connection (wired or wireless) or not. The best selection here is NO, so choose "I don't want to connect...".



3. Select Third Party Programs


Third page of Ubiquity asks you about whether to install or not for third party programs (some proprietary software, some covered with proprietary patent laws). Example of these programs are Adobe Flash Player and Fluendo GStreamer framework. The best selection here is NO, so choose nothing here.



4. Select "Something Else" Partitioning


Fourth page of Ubiquity asks about partitioning style, whether you want the automatic or the manual way. The best choice is always the manual way, and don't believe any automatic partitioner, except your HDD is empty. So the choice here is Something Else.



5. Partitioning


The most important part (and the most dangerous) is the fifth step, manual partitioning (but it's completely harmless if your HDD is empty). What to do here is basically two things: 1) creating main partition (namely "/"); 2) creating swap partition (namely "swap"). Pay attention here so you don't make any mistake, otherwise you may destroy all your data.

To create main partition, select a partition you have prepared before > click Change button > a new window "Edit Partition" comes >
  • 1) determine the partition size
  • 2) determine Use as: Ext4 journaling file syste
  • 3) select "Format the partition"
  • 4) determine Mount point: /
  • click OK. 
For example: I choose /dev/sdb2 as my main partition with partition size = 20 GB, filesystem = Ext4, Format = yes, Mount point = /. It means, this choice of mine will install elementary OS into /dev/sdb2 (second partition) of my /dev/sdb HDD (second HDD).




6. Creating Swap


To create swap partition, select a partition you have prepared earlier > click Change button > a new window "Edit Partition" comes >
  • determine Size: 2 GB or more*.
  • determine Use as: swap area. 
  • Click OK.
For example: I choose my /dev/sda3 as swap partition. This was actually an empty partition.

*) You don't have to use old formula "swap = 2 x ram amount" anymore for computers nowadays. It is considerably safe to give only 2 or 4 GB swap for most of todays desktop computers (including laptops). Few exceptions if your jobs require swapping (rare case), or you would use hibernation. Read Ubuntu SwapFaq document for detailed explanation.





7. Partitioning Summary

Seventh step is examining partitioning summary. Ubiquity will inform you what partition will be formatted or created. Please read carefully, make sure the two partition you created earlier are correctly the two informed here. Don't make mistake, don't format wrong partition. This is the last chance to revert back before Ubiquity formats your partitions.

For example: I set two partitions /dev/sdb2 as main, and /dev/sda3 as swap. So Ubiquity inform me partition #3 of sdb and partition #2  of sda respectively. They are correct. Read carefully before continuing.




8. Select Region

Eighth step is selecting region. Just select your region or your country. This will determine your time zone automatically. For example, I choose Asia, Jakarta.




9. Select Keyboard


Ninth step asks you for your keyboard layout. For most users, default selection (English US, English US) is safe.




10. Create Username


Tenth step asks you the desired username and password for the elementary OS. Select "Require my password to log in" so anyone should enter password to use the system.



11. Wait for Installation Process


Eleventh step is merely waiting until the installation process is done. This process will also detect any other operating system installed in your computer, then shows list of systems selection (people call it: bootloader) at your booting time.

12. Finish


The last step is seeing Installation has finished statement from Ubiquity, which means your elementary OS Loki has successfuly installed. Go restart to use it.

Create a Restore Point for Windows 7 or Vista’s System Restore

If you are thinking of installing an application but aren’t quite sure what it’s going to do to your computer, I would absolutely recommend creating a restore point before you install that application, and here are the steps to do so. Note that most application installs automatically create a restore point, but you can do this if you are really worried. Open up the Start Menu and right-click on “Computer”, and then select “Properties”. This will take you into the System area of Control Panel. Click on the “System Protection” link on the left hand side. Now select the “System Protection” tab to get to the System Restore section. Click the “Create” button to create a new restore point. You’ll be prompted for a name, and you might want to give it a useful name that you’ll be able to easily identify later. Click the Create button, and then the system will create the restore point. When it’s all finished, you’ll get a message saying it’s completed successf...

How to Clean Up Your Messy Windows Context Menu

One of the most irritating things about Windows is the context menu clutter that you have to deal with once you install a bunch of applications. It seems like every application is fighting for a piece of your context menu, and it’s not like you even use half of them. Today we’ll explain where these menu items are hiding in your registry, how to disable them the geeky way, and an easier cleanup method for non-geeks as well. Either way, your context menu won’t look like this one anymore… Cleaning the Context Menu by Hacking the Registry If you want to clean things up the truly geeky way, you can open up regedit.exe through the start menu search or run box, and then browse down to one of the following keys… sadly the context menu items are not stored in a single location. Most of the menu items that used for all files and folders can be found by looking at one of these keys: HKEY_CLASSES_ROOT\*\shell HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers HKEY_CLASSES_...
