How do I open an .iso file (Firefox won't work)?

Why isn't what I downloaded to install Ubuntu an executable file?

An ISO is a sort of a CD but as a file (see). You can write an ISO to a CD and this one can be written to a CD or USB flash to create a Live disk to install or try Ubuntu. – chesedo Feb 18 '14 at 4:55
Are you on windows or ubuntu? – Amith KK Feb 18 '14 at 5:06

Burn your ISO file to the Media such as DVD or CD and Boot it to get install, you can't Open the ISO file using Firefox, Burn it using some software's such as Nero in Windows Machine, Use k3b in Linux to Burn the ISO file to CD or DVD

You can open .iso files in nautilus in easy way just navigate to the *.iso file , then Right click -> Open with Archive Mounter.

Or you can install the Furius ISO mount application

sudo apt-get install furiusisomount

I think that this will not help the OP that asked "… to install Ubuntu". He or she is clearly expecting the classical .exe or .MSI installer of Windows... – Rmano Feb 19 '14 at 6:30
nope the second part is another question – Maythux Feb 19 '14 at 6:32

Alternatively there's 2 ways to install an ISO, Flash Drive or DVD. if you i have a 2GB flash disk, then try these

  • launch startup disk creator application from Ubuntu
  • select the ISO file from the top parameter
  • select the flash drive from the second parameter (ONLY AFTER BACKING UP YOUR DATA)
  • Erase the disk and then make startup disk
  • then reboot with flash drive as an option from BIOS

or you can just right click on the ISO file and select Write to Disk option after you have inserted your CD/DVD and once it's detected the media, you can click on Create Image

Here's a screen shot of how the application looks like enter image description here

He has no Ubuntu, only ISO, so it would be better to use Universal USB Installer from Windows. – Danatela Feb 18 '14 at 5:54
Sorry, i didn't know that. try unetbootin or USB Installer on Windows or MAC – Olu Feb 18 '14 at 6:16

Ubuntu is not a program, is an operating system.

You are advised to

a) backup your data before trying to install it and

b) read ALL of and be sure to understand it before starting.
