Burn an ISO File
As outlined in the Download Manjaro page, an ISO is not simply a 'drag and drop' or 'copy and paste' duplication of Manjaro's installation files. It is in fact a copy of the raw computer code that makes up the files themselves. This is why it is necessary to use a software burning application to 'burn' an ISO file, that is, convert its raw code into the files onto a physical medium such as a DVD or USB flashdrive / datastick in order to use it. Once burned / converted, the files on that medium can then be used to run Manjaro directly without having to install it to your system (referred to as Live-CD or Live-USB mode), and/or install Manjaro on your system. Again however, it will not be necessary to to burn an ISO if you intend on running Manjaro in a virtual machine environment using Oracle's Virtualbox. This is because Virtualbox is able to read ISO files directly as virtual disks.
Burning to CD/DVD in Linux
Several different software burning applications - if not already installed - should be available for installation from your distribution's Software Center / Software Manager / Package Manager / repositories. Popular burners include XFBurn, K3b, and Brasero. Which one you may choose is entirely down to personal choice. However, a guide to burning your downloaded Manjaro ISO using Brasero has been provided below:
1. Insert a Blank CD/DVD (use a DVD if burning an ISO for anything other than the NET Edition)
2. Start the Brasero software burner
3. Click the Burn Image - Burn an existing CD/DVD image to disc button to open the Image Burning Setup window.
4. Click the button beneath the title Select a disc image to write to open up your file manager. Locate and double-click the downloaded ISO file to load it. Upon automatically returning to the Image Burning Setup window, note that the ISO file is now listed as the disc image to write.
5. Underneath the title Select a disc to write to the blank CD/DVD inserted should already have been automatically listed. Otherwise, click the button to select it manually.
6. Click the properties button to open the properties window, and then click the button beneath the title Burning Speed. Again, it is strongly recommended to select the slowest speed available. Once selected, click the Close button.
7. Click the Burn button to start the burning process. If necessary, follow any on-screen instructions provided.
Burning to a CD/DVD in Windows
In Windows 7 and later, support for burning an ISO to DVD is built-in. Simply right click on the on .iso file and select "Burn disk image". This will bring up a series of dialogues to walk you through the process.
For Windows Vista or older versions of Windows you will need to download 3rd party software. Several free software burner applications are available for Windows. One such tool is DeepBurner. The portable version can be downloaded from here.
Writing to a USB Stick in Linux
This section describes how to write a Linux ISO file to USB.
Windows ISO files are notoriously difficult and requires special attention.
Using the Terminal
To burn the iso on an usb stick, enter the following command in a terminal :
Where [drive letter] is the letter of your removable device. Please note that it is the device (e.g. /dev/sdb), and not the partition number (e.g. /dev/sdb1).
To find which drive letter it might be write:
How you can check ISO
- Isohybrid have 2 partitions, you can check also with gparted after burn the iso on an usb stick.
How create isohybrid
- or for UEFI
Using a Burning Application
ImageWriter should be available for installation from your distribution's Software Center / Software Manager / Package Manager / repositories. Once Imagewriter has been downloaded and installed, ensure that your USB stick is plugged in before starting it.
A brief guide to writing the Manjaro .ISO image has been provided:
1. Click on the centre icon
2. Navigate to where the ISO image has been saved and select it
3. Ensure that your USB device has been selected from the drop-down menu
4. Click on the Write button
5. After the Write process has finished, reboot your system
Writing to a USB Stick in Windows
Rufus Rufus is a utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc.
When you use Rufus to write a Manjaro Live ISO to USB you must select DD mode when prompted to use standard or DD mode.

Writing to a USB Stick on a Macintosh
As a Unix variant, macOS uses a similar approach to Linux. All commands below should be run in the Terminal application. Commands using sudo may prompt for your password; this is expected.
After you've inserted your USB drive, identify it using diskutil:
/dev/disk0 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_APFS Container disk1 1000.0 GB disk0s2 /dev/disk3 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *7.8 GB disk3 1: Windows_NTFS MYUSBDRIVE 7.8 GB disk3s1
Note the identifier disk3s1 in this example.
Unmount the drive with the command:
Volume MYUSBDRIVE on disk3s1 unmounted
Now you can use dd to write to the raw device:
787+1 records in 787+1 records out 3303161856 bytes transferred in 2470.782563 secs (1336889 bytes/sec)
The USB drive can now be removed from the computer and used to boot Manjaro.
