Prior to burning your downloaded ISO image (or using it as a virtual disc in Virtualbox), it is '''strongly''' recommended that you first check that it hasn't been corrupted. The consequences of not doing so - especially if you intend on installing Manjaro as your main operating system - should be obvious (i.e. a corrupted image will result in a corrupted installation).


To do so, you must first download the appropriate ''checksum file'' from the same ''Sourceforge'' website folder as your chosen ISO image. A checksum file will have the same name as the ISO image that it is to be used with; the only difference is that it will end in either '''-sha1.sum''' or '''-sha256.sum'''. For example, the appropriate checksum files for the ''manjaro-xfce-0.8.1-x86_64.iso'' file (64 bit Manjaro release 0.8.1 with the XFCE desktop) would be:  
Installation guides for every release of the '''full edition of Manjaro''' (i.e. complete with a desktop environment, popular software applications, and codecs), have been provided bellow for both beginners and experienced users. These guides may also be used to install Manjaro as a main operating system, or within a virtual machine environment using '''[https://www.virtualbox.org/ Oracle's Virtualbox]'''. In either instance, if necessary, guides are also available to help you '''[[Download Manjaro]]''', '''[[Check a Downloaded ISO Image For Errors]]''', and to '''[[Burn an ISO File]]''' to disc or USB flash-drive / data stick. Otherwise, rebooting your computer (or starting your virtual machine) after connecting your installation media should be sufficient to start the process.  If you find that your computer continues to boot into your existing operating system despite this, then check that:


* manjaro-xfce-0.8.1-x86_64'''-sha1.sum''', and/or  
* The ISO Download and/or installation media has not been corrupted, and that
* manjaro-xfce-0.8.1-x86_64'''-sha256.sum'''
* Your disc drive or USB flash-drive - depending on which you are using to install - is listed higher up in the boot order than your hard drive (i.e. that they will be booted from first).  


Checking and amending your boot order if necessary will require either going into your computer's ''BIOS settings'' (if installing Manjaro as your main operating system), or Virtualbox's ''System Settings'' (if installing in a virtual machine).


== SHA1 and SHA256 ==


The 'sha' part of the checksum file name stands for <u>S</u>ecure <u>H</u>ash <u>A</u>lgorithm. This algorithm is used to generate a particular code unique to the downloaded ISO image. '''sha1''' and '''sha256''' are different versions of the algorithm that you can use to do this. Whilst sha1 is the most commonly used version, sha256 is a later and more secure version. Which you decide to use is entirely your choice. '''However, if you are unsure, then it is recommended to use sha256'''.
= Manjaro 0.8.2 =


The checksum file itself is just a text document that contains a code that should match the code generated by the sha1 or sha256 algorithm. As such, if the code generated from the ISO file matches that contained in the checkum file, then the ISO is fine. Otherwise - if the two codes don't match - then it means that the ISO file has changed in some way, most likely due to being corrupted. You can think of it like someone using a secret password to identify who they are: if they provide the wrong password, then something is obviously amiss!

Don't worry if this all sounds a bit much - it's actually very straightforward and easy to use!


In addition to the standard '''Stable Installer''', Manjaro 0.8.2 also provides the experimental '''Testing Installer''', which is <u>specifically aimed at more experienced users</u>. The Testing Installer provides several new - and advanced - features not otherwise found in the Stable Installer, including support for the:

* Unified Extensible Firmware Interface ('''[http://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface EFI]''')
* B-tree file system ('''[http://en.wikipedia.org/wiki/Btrfs btrfs]''')
* Redundant Array of Independent Disks ('''[http://en.wikipedia.org/wiki/RAID RAID]''') storage system


To check the integrity of your downloaded file, it will be necessary to first open the downloaded checksum file using a text editor such as ''Gedit''. Depending on whether you intend to use sha1 or sha256, ensure that you have downloaded and opened the appropriate checksum file (i.e. ending in -sha1.sum or -sha256.sum, respectively) as they will contain different codes. Once the checksum file has been opened - and the code is visible - open up your terminal and change to the directory where your downloaded ISO is stored. For example, if your ISO file is located in the default ''Downloads'' folder, you would enter the following command:


cd Downloads

Please note however, that while there is no need to manually partition your hard disk or edit any configuration files, '''using this guide will result in completely erasing your hard disk during the installation process'''.

The command to then perform a checksum uses the following syntax:

For example, the following command will use sha256 to generate a code from the 64 bit Manjaro XFCE 0.8.1 ISO. The code generated can then be compared to the code provided by the appropriate sha256 checksum file:

'''2. [[Installation Guide for Experienced Users 0.8.1-2|Installation Guide for Experienced Users]]''': This guide covers the ''manual preparation'' of your computer's hard disk, where partitioning must be undertaken by hand.

As some technical knowledge and experience is assumed, the guide provides less detailed explanations.


As illustrated, in this instance both codes match, thus confirming that the downloaded ISO file is completely fine. The following command would use sha1 to undertake exactly the same task:


sha1sum manjaro-xfce-0.8.1-x86_64.iso

Where satisifed that both codes match, then it is safe to proceed to either burning the ISO to your chosen installation, or using it immediately in Virtualbox. Otherwise, it will be necessary to delete the ISO image and download it again.

It will be necessary to download and install a checksum utility application. Several free versions may be found on the '''[http://download.cnet.com/ Download.com website]'''.

Overview

Tip
For the best results, please ensure that Manjaro is connected to the internet prior to starting the installation process.


Installation guides for every release of the full edition of Manjaro (i.e. complete with a desktop environment, popular software applications, and codecs), have been provided bellow for both beginners and experienced users. These guides may also be used to install Manjaro as a main operating system, or within a virtual machine environment using Oracle's Virtualbox. In either instance, if necessary, guides are also available to help you Download Manjaro, Check a Downloaded ISO Image For Errors, and to Burn an ISO File to disc or USB flash-drive / data stick. Otherwise, rebooting your computer (or starting your virtual machine) after connecting your installation media should be sufficient to start the process. If you find that your computer continues to boot into your existing operating system despite this, then check that:

  • The ISO Download and/or installation media has not been corrupted, and that
  • Your disc drive or USB flash-drive - depending on which you are using to install - is listed higher up in the boot order than your hard drive (i.e. that they will be booted from first).

Checking and amending your boot order if necessary will require either going into your computer's BIOS settings (if installing Manjaro as your main operating system), or Virtualbox's System Settings (if installing in a virtual machine).


Manjaro 0.8.2

Tip
It is recommended that unless there is a specific reason to do otherwise, most users - beginner and experienced alike - should use the standard Stable Installer for the best results.


In addition to the standard Stable Installer, Manjaro 0.8.2 also provides the experimental Testing Installer, which is specifically aimed at more experienced users. The Testing Installer provides several new - and advanced - features not otherwise found in the Stable Installer, including support for the:

  • Unified Extensible Firmware Interface (EFI)
  • B-tree file system (btrfs)
  • Redundant Array of Independent Disks (RAID) storage system
